We all have our own memories of "Mean Girls" (and guys), but it is somewhat comforting to know that the world's sexiest supermodels (aka the Victoria's Secret Angels) suffered teasing and taunting through those terrible teen years over the very assets that have brought them fame today.

"Growing up, I had a lot of friends that were boys but they certainly weren't all over me, it was the opposite," Karolina Kurkova told Pop Tarts backstage while getting primed and prepped for the VS Annual Runway Show, which airs Tuesday night.

"Most girls were already women, and here I was so tall with really long arms and really long legs. Boys definitely didn't think I was cute," she said.

However, the Czech-born beauty didn't let nasty name-calling deny her of her dream.

"I've overcome it all — you have to accept yourself, be confident and believe in yourself because the audience can tell if you don't," she said. "You just can't look around and look at her body and look at her abs, you have to accept yourself. I love my body, I love myself."

And while busty Brazilian Izabel Goulart also has every reason to totally love herself, there was once a time when she thought she was the least sexy specimen in her school.

"No boys for me growing up! I was so skinny and tall. Everybody called me a giraffe," Goulart said. "I had no boobs and no butt and nobody liked me, I was so lonely. All the boys would come to me and want advice because they wanted my friend. But nobody ever wanted me — high school was a very sad, lonely time."

But one Australian "Angel" face who doesn't need to worry too much about being ugly or unappealing is the latest leggy lingerie lass to replace Gisele Bundchen, fresh-faced Miranda Kerr.

"Everyone feels their most gorgeous when well-rested, but the good news is that the makeup they use on us makes us look good even if we don't feel good," Kerr said. "But it's so important to embrace what you have been given, that's the most important thing, and just to be grateful. Someone will always have something better than you, but then there are always plenty of people that are less fortunate."

And while the dimple-faced doll is now reportedly "fortunate" enough to be dating Orlando Bloom (Pop Tarts popped Bloom sitting by the side of the stage during the taping of the fashion festivity and canoodling with Kerr at the after-party), she wasn't always such a glamorous gal.

"I was such a tomboy growing up — boys didn't think of me as one of the sexy girls," Miranda said. "I was just someone they would beat around with and ride motorbikes with. Now look at me — I'm quite the opposite."

But something else aside from being "not sexy" brought tears to the eyes of this stunning supermodel as we spoke. Click here to find out…

However, it seems Miranda could trade tales with busty buddy Marisa Miller, who once upon a time would have rather worn a wet suit than a Wonderbra.

"It's funny because growing up I was a tomboy, played a lot of sports, so it's funny that my job has taken this direction because I'm really like a T-shirt and jeans kind of girl and my friends always laugh when they see me, because they know me and I'm really low-key," the California native told us.

"But at the same time I have become a girly girl and that's what I love about the job — being able to explore this side of yourself. Victoria's Secret makes it very fun to be a girl."

Britney Bookstore Alert!

Britney Spears was spotted out and about on Wednesday night at a somewhat unusual place y'all … a Barnes & Noble bookstore!

The four-eyed crooner caused a "Crazy" scene as she pranced past all the self-help and psychoanalysis books to finally buy what she was looking for: a Starbucks latte.

However, our super staff spies told us that they let Brit hide in their kitchen while they whipped up her wonder drink, and that eight LAPD officers were called in to assist Britney back out to her banged-up Benz.

But one shopping adventure that sounds a little more Spears-like was a reported recent trip to an X-rated store, and (shock!) she was buying panties!

However, according to Us Weekly, the Britster was mad that she wasn’t allowed to try on the cotton coverings after stripping down and apparently stormed out, giving herself a five-finger discount on a wig on the way.

But speaking of spotting and shopping, Pop Tarts has also been told the latest "Dancing with the Stars" sensation (and now sadly single) Helio Castroneves won't be professionally swapping speed for sambas in the near future.

According to our sources, the Indy man missed his mileage so much during his "Dancing" days that he had a special RITMO Indy Car Chronograph watch made up to look like the rubber tires on his wheels.

"And he told us it was his lucky charm," said our insider. "So it obviously worked."

And what happens when you put a party, shoes and “Big” boys together? No, you don’t get “Sex & the City” — you get a whole bunch of basketball pros comparing who has bigger feet.

Pop Tarts was present on Wednesday night as the NBA’s Carmelo Anthony launched his incredibly large shoe line MELO M4 at a Jaguar dealership in West Hollywood.

And even though the street outside was lined with gangs of gals trying to get a glimpse of the gold-blinged Denver Nugget, he chose instead to test out those super shoes with Pop Tarts on the dance floor until the wee hours.
