We rounded up the stories about the times that made your favorite teen stars cringe, right here. Get ready to LOL!

Selena Gomez takes a spill.
Selena Gomez of “Wizards of Waverly Place” loves her fans, but she also adores footwear. When she decided to brave a set of stairs in a pair of killer heels to meet up with some admirers, things didn’t quite go as planned. Here’s what she told reporters at a red-carpet movie premiere: “I was doing a live taping of my show, and I fell because I was wearing these high heels down the stairs after saying hi to my fans. That was pretty bad.”

Justin Bieber gets bashful.
He’s a home-schooled pop phenom now, but before Justin Bieber blew up, he attended a regular school and had regular kid probs. “I was in class doing a project, and one of my best friends thought it would be funny if he would kind of change my project around,” Justin told a teen mag. “He put a picture of something stupid on it, and everyone started laughing at me. I felt really bad.”

Taylor Swift has tall troubles.
Country singer Taylor Swift is a towering beauty, but sometimes her height can lead to some really awkward moments. “I’ll always be hitting my head on the side of a car or going through door,” she once admitted to a music reporter. “I think I’ve gotten minor concussions from hitting my head on things.”

Miranda Cosgrove’s pal pulls a prank.
Miranda Cosgrove and her BFF were spying on a guy when the “iCarly” star’s friend pulled a fast one! “My best friend and I, we’re always driving by this guy’s house she really likes,” Miranda told a magazine. “This time, she was begging me to walk up to his house to see if he was home. So I got out of the car and went up to look into the house like a total stalker, and she drove away pretending to leave me there! She came back like 30 seconds later, but I thought she had abandoned me.”

Josh Hutcherson has not-so-smooth moves.
“The Hunger Games” star Josh Hutcherson should have no problem impressing dates, but he recently confessed that he could use a little more finesse in the cuddle department. In a magazine interview, he talked about trying to get close to a girl he liked, when a fumble nearly ruined the evening! “I was on a date, and we were sitting at dinner,” explained Josh. “I tried to put my arm around her -- I was doing the yawn thing where you lift your arms up. As I did that, I hit the table and spilled a drink.”

OK, we’re not talking about coercion, persuasion or -- yikes! -- temper tantrums. But if you want to get someone on your side in any given situation, there are some effective (and ethical!) tactics you can use to sway it your way. We’ve tidied it up into an art form, right here.

“I want my parents to let me stay out an hour later on the weekends. Is that so much to ask?”

The Art of Accepting as Is

Whether you’re looking for a later curfew, more allowance or fill-in-the-blank-here, the first step is to do ... nothing. Your parents know whatever privileges you’re after, right? If not, go ahead and ask. But once you’ve asked, do not bring it up again for at least 30 days. At that time, calmly ask again.

Repeat this pattern until they eventually agree. And the only reason they’re likely to go for it is because you didn’t hassle them. You demonstrated maturity, patience and acceptance of their decisions. Works like magic!

“This one girl in our group snubs me, and it makes me uneasy. I want her to be nice!”

The Art of Attitude Adjustment
First off, we know it’s tough, but never take anyone else’s attitude personally -- even if it comes off that way. You really don’t know what insecurities or other issues this girl might have, so approach the situation from a place of non-judgment.

Also, remember that no one can make you feel uncomfortable. This is tricky too, but how you react to anything is always your choice. Turn this around by adjusting your demeanor. Relax, and treat her the same as you would like her to act toward you. Start out by subtly smiling and nodding at her. As long as you’re sincere, the tension will gradually fall away.

“My teacher gave me a totally unfair grade, and I want it changed.”

The Art of A+ Appreciation
If you genuinely feel the grade is unfair, make arrangements to see your teacher after class. But instead of storming in and waving your paper in protest, approach him or her with an air of gratitude.

Being authentic -- not fake -- and thank your teacher for taking the time to chat with you. Then make your case. Rather than griping, “I spent hours working on this project,” talk about how much you learned and gained from the assignment. If the teacher refuses to alter your grade, ask about extra credit. Whatever the outcome, continue to be appreciative, and you can be sure next time Teach is teetering between giving you a C+ or a B-, she’ll lean toward the better grade!

Ah, fear. Whether it’s about acing a final exam, talking to your crush or hitting your parents up for a later curfew, the one thing that can throw you into a tailspin is fear. It’s a powerful emotion, but we’ll walk you through some ways to say, “Hey, fear! You don’t scare me!”

“I have to do a class presentation, and it counts as a big part of my grade. I’m totally nervous.”

Fear Tactic: Feel it!
Don’t fight it. If you want to shake the jitters, give in to ’em a little. As you prepare for the big day, whenever you feel a wave of fear come over you, feel the discomfort of it. Fear multiplies and super-sizes when you resist it, but feeling the fear allows it to move through you (buh-bye). Then make it a point to have fun putting together that project -- and carry that positive vibe into the classroom.

“I’m going to a party with my crush, and I’m freaked out because his ex-girlfriend is going to be there. Help!”

Fear Tactic: Face it!
This is a good time to get in front of the mirror and give yourself a pep talk. Get grounded in your confidence and don’t carry with you any icky feelings, such as jealousy or insecurity. Be your absolute best self at the party, and boldly but humbly confront the face of fear by introducing yourself to the ex-GF. Just smile, make eye contact and warmly say, “It’s so nice to meet you.” Was that so bad? Now enjoy the par-tay!

“I want to hit up my parents for more allowance, but I’m scared to even approach them about it.”

Fear Tactic: Forget it!
We’re not telling you to give up on your dream of getting your parents to pad your allowance (or whatever privilege you want). But we are telling you to stop thinking about it so much. Overanalysis can cause emotional paralysis. So just tuck this subject away in the back of your mind. The next time you see an opportunity -- that is, when your parents have their guard down and you’re feeling particularly brave -- just take a deep breath, walk up and just ask.

“I’m trying out for an all-girls ice hockey league, and I’m so afraid I won’t make the cut.”

Fear Tactic: Flip it!
The thing about fear is that it often feels very similar to another emotion: excitement! Is your heart racing? Is your brow sweaty? Shift your thinking from being afraid to being totally geared up for an awesome challenge! So what if you don’t make tryouts? You enjoyed yourself in the meantime. Now you can spend time improving your ice skills, or you can take up another activity. It’s entirely up to you; life is an adventure for the fearless!

You abso-tootin-lutely love your girls. Their silly antics have you in a fit of daily giggles, and they always know just the right thing to say to turn your frown upside down. But sometimes the road to friendship isn’t all fun. Read on to find out how you can end friendship drama once and for all.

“My BFF always copies my look!”
You work hard to have a standout style, so it can be mucho a-ggrrr-vating when a bestie snags up your original fashion finds.

The Sunny Side: Ever hear the old saying, “Imitation is the best form of flattery?” It’s obvious you’re a trendsetter -- not a follower. So before ya huff and puff that your girl has played copycat for the umpteenth time, remember that it’s only because you’ve paved the way. She’s not trying to be you; she just loves your taste. So use your fashion sense to help your BFF find a unique style all her own.

“My friend always ditches me for boys.”
Your girl is with you through thick and thin, but the moment a brown-haired babe enters the picture, she goes missing.

The Sunny Side: Put yourself in her shoes and try to be understanding. Remember when you were totally gaga over that guy and you were anxious to spend every moment you could with him? Your girl feels the same way. Don’t worry, though; once the starry-eyed phase is over, she’ll be back by your side. Can’t wait? Let her know you miss her. But be confident enough in the friendship to let her enjoy her trip on Cloud Nine.

“My girlfriend mooches off me, and I don’t get much allowance!”
Sure, you might have thought buying a cup o’ joe for your gal at Starbucks or picking up the popcorn at the movies was no biggie. But now your girl is outta control.

The Sunny Side: Since your girl doesn’t have the cash to cover, think of other alternatives that you can do for free. This way you’ll both save money! You don’t need to spend dough to have fun with your girl, so stick to zero-cost outings and adventures when you’re hanging with your fave gal pal. Hit up a nature trail, break out the board games or bake a batch of brownies!

You’re growing up. Lotsa changes going on, huh? Confusing, yeah. But no need to freak out about it. It’s known as puberty, and it’s totally normal. Here’s the lowdown on what to expect so you don’t get caught off guard.

Breast-ology
Are your breasts beginning to bud? Cool! They’ll gradually get bigger and fuller, and they might even become a little sore. One breast could grow more than the other at first, but they’ll eventually even out. (Most women have one that’s slightly larger, but it’s usually not too noticeable.) How big or small your boobs become depends on genetics. So when are they fully developed? It usually takes two to three years!

Hairy Scary?
If you haven’t already, you’ll soon grow hair in the pubic area -- that part of your bod that extends from your lower tummy to between your legs. Initially, the hair is soft and there isn’t much of it. Later, it gets a little longer and usually becomes kinky and curly. Right around the time you get pubic hair, you’ll also sprout some under your armpits.

Ugh, Zits!
The pores in your skin produce more oil during puberty, especially on your face. This can cause pimples to pop up. If you have a problem with acne, gently wash your face with antibacterial soap several times a day. Hopefully, getting rid of the excess oil will zap your zits. If it’s severe and won’t clear up, see a dermatologist.

Periods. Period.
Before you start your period, you’ll probably notice yellow or white stains inside your underwear. This is natural moisture from the vagina. It’s perfectly normal and is a sign that menstruation will probably start in about six to 18 months. Although most girls get their first period between 11 and 14 years old, it can come as early as 8 or as late as 17. Since it’s pretty unpredictable, it’s a good idea to have some pads stashed away for when it does catch you by surprise.

Oh, No … B.O.
Your sweat glands become larger and more active as you get older, so you sweat more. And it doesn’t exactly smell so fresh. That means it’s time to pay particular attention to your hygiene. Be sure to wash under your arms when you shower, and by all means, get yourself a stick of deodorant or antiperspirant.
