Hot Gallery: From Geeks to Glamour Girls!

Glasses, braces, and and awkward bangs—back then Elisabeth was rocking every cliché nerd-dom had to offer.

Best known as one of the hosts of The View, Elisabeth is also a proud wife, mother, author, and celiac. Her passion for running and her G-free diet just may be the secret to her makeover success—check out her book, Deliciously G-Free, and try it for yourself.

Already an Oscar winner for her role in The Piano (she was only 11 when she won, making her the second-youngest person ever to win), this teen relied more on her acting chops than her looks.

Using her girlish innocence as sex appeal as Sookie on True Blood, Paquin scored her husband, costar Stephen Moyer, and numerous Golden Globe nominations (including a Best Actress win in 2009). Before she was a vamp-loving fairy, she made the most of teen angst in films like Hurlyburly, A Walk on the Moon, and Almost Famous, shifting seamlessly into her new role as sexpot. The final season of True Blood just ended, so we're looking forward to what she does next.

Trading in her glasses and bob for heavy eyeliner and attitude, Avril burst onto the music scene in 2002 with hits like "Complicated" and "Sk8er Boi," possibly even inventing her own style—pop-punk tomboy? I bet they didn’t have their own high school clique.

With several albums, tours, hits, hair colors, and even a marriage under her belt (her ex is Deryck Whibley, lead singer of Sum 41), confidence seems to be the secret for this young singer/songwriter/entrepreneur’s transition to glamour-puss. Known for her lyrical tales of romance, her self-titled album Avril Lavigne is her most fun to date. For a nonmusical dose of Avril, you can check out her fashion and lifestyle brand (Abbey Dawn), her fragrances (Black Star and Forbidden Rose), or her charity, the Avril Lavigne Foundation.

Back when this child of destiny still needed a last name, she was already on her way to being Irreplaceable—she’s been singing since she was 7.

Though this wife of Jay-Z and mother to Blue Ivy is a single lady no more, we’ll always have the dance. (Go ahead, take a dance break.) Evolution seems to be the key to this music and fashion icon’s success, with both her eclectic fashion lines Deréon and House of Deréon and her latest album, Beyonce. "The more mature I become and the more life experiences I have, the more I have to talk about.… I really want people to think when they listen to my music. I want them to feel more than 'OK, I'm at a party, I'm dancing,'" she said about album 4.OK, B, we also think you’re hot. Take a listen.

Sure, this fresh-faced girl next door looks like the poster child of a Neutrogena spokesperson (and she is now), but who would think Miss Prim and Proper would become such a badass? (Hello, Alias!) Garner told The Mirror in 2004 that she was a big time geek in school. "I was a real nerd," she says. "I wasn't the popular one, I was one of those girls on the edge of the group. I never wore the right clothes and I had a kind of natural geekiness. I was in the school band and I think that has a bit of a stigma at the age of 13. If you'd asked me what I wanted to be, I would have said something like a librarian."

Proof that you can have it all, this half of Bennifer uses her mixture of tough, funny, and sincere to give us hits like Daredevil, 13 Going on 30, Juno, and Arthur. (Kids Violet, Seraphina, and Samuel aren’t bad either.) The Odd Life of Timothy Green proved to be further evidence that if you stay true to yourself, success will follow.

We’re guessing this athlete was more likely to be voted J.T. look-alike than future Oscar nominee. (Tell me she doesn’t look like J.T. in drag. You can’t.) We’re not sure what the “paw print” emblem signifies on Jennifer’s sweater here in middle school, but guessing it did not win her a “most stylish” moniker. With the soon to be released The Hunger Games film this month (anticipated to be a bigger sensation than the hugely popular Twilight series, if you can even believe it), the 21-year-old actress is about to be a house-hold name. But before landing the most coveted role in Hollywood, Jen was a tomboy who played on an all-boys’ basketball team in school and admitted once she “went through a wood-chopping phase.” A-hem, "woodsy" geek alert!

Best known for her role in The Hunger Games (and the hot red dress she wore to the Oscars), Jen has the ability to radiate both strength and sexy. Only 24 and already a household name (maybe it’s not so bad to follow in J.T.’s successful footsteps), she can be seen next in The Hunger Games: Mockingjay.

Behind these hazel eyes lies the future heartache that would help make her the first American Idol in 2002.

Our lives would suck without you, Kelly. "Because of You," millions of women are indeed feeling "Stronger," letting you deliver the lyrical smackdown on their behalf. This empowered songstress—who defies those who tell her she has to be a certain size to be successful (go, girl!)—released a Christmas album, got married and had her first child! Go girl indeed!

Who could have predicted from this photo that Michelle O would grow up to become a style icon the likes of Jackie O?

More than just good lighting and makeup, we bet it’s Michelle’s ability to balance career, family, and health that give her that glow. Let’s move indeed! Be a part of Let's Move!

Paula had fame down to a science from an early age, making the leap from Lakers cheerleader to pop sensation to reality-show judge. According to People, Abdul was the class president and on the science and debate teams, and played the flute in her school’s band. Way to make us all look like slackers!

Forever our girl, Paula sang and choreographed her way into our hearts with hits like "Straight Up," "Opposites Attract," and "Rush Rush" before she survived Simon Cowell not once, but twice, proving she has the X factor (no matter what Simon thinks). Relive Paula Abdul’s "Forever Your Girl" video.

Who knew this daughter of Quincy Jones and Peggy Lipton would turn into such a bombshell? This Harvard grad said to Playboy in 2011 that she was a square as square can be. "I came out of the womb reading books and thinking about my next project. I’m a born nerd." She continues by admitting, "In high school I never drank, I never smoked, I never smoked weed. I was president of the varsity club and was on the math team and then student government."

With a string of hits under this Harvard grad’s belt, like Parks and Recreation, The Office, Boston Public, The Social Network, Our Idiot Brother, The Muppets,and I Love You, Man, it’s clear that talent runs in the family. She also got daddy’s pipes, contributing to many a soundtrack and making her a triple threat—writer/actor/singer. See Rashida sing the praises of singledom on Parks and Rec.
