Tiffani Thiessen started out as Kelly Kapowski in Saved by the Bell. She inspired milllions of male fantasies during her time at Bayside High, and she's only gotten hotter with age.
K-Stew got her big break at the age of 12, co-starring with Jodie Foster in Panic Room. She went on to become one of the most bankable actresses in Hollywood, thanks in no small part to stylish good looks.
Emma has come a long way since Hogwarts. She now has Hollywood, the fashion world, and millions of men undr her spell.
Kirsten Dunst hit it big at a young age, landing high-profile roles in Interview With the Vampire and Jumanji before she reached her teens. She grew into a very attractive young woman, and has continued to work steadily.
It's hard to believe that Alyssa Milano is 42, not only because we can't believe Who's the Boss was that long ago, but also because she continues to get hotter with each passing year.
Christine Lakin got her start as the tomboy Alicia "Al" Lambert on the ABC sitcom Step By Step. At the time she was cast, we're guessing producers didn't expect her to grow into one of the most naturally gorgeous actresses in Hollywood.
She's come a long way since Wednesday Addams. Christina accounced the sexpot stage of her career with her mostly-nude role in Black Snake Moan.
Natalie Portman gained acclaim for her role in Leon: The Professional when she was just 13. She went on to become one of the most acclaimed (and sexiest) actressed in Hollywood.
Katie Holmes inspired millions of crushes as Joey on Dawson's Creek. Now that she's free of the Tom Cruise's creepiness, we can all resume lusting after her.
Melissa Joan Hart
Melissa explained it all as Clarissa. But there might be an explanation for how hot she is these days.
Alicia became the it-girl of the late '90s as Cher in Clueless. She may not be an A-listed anymore, but she's still crazy hot.
Speaking of Clueless, remember Cher's friend, Stacey Dash? These days she's a Fox News correspondent, and while you might not agree with her politics, there's not denying that she's smokin' hot.
Drew was one of the original troubled child stars. Fortunately, she pulled herself out of the tailspin to become one of Hollywood's most bankable actresses. As a bonus, she remains super hot.
Given her myriad academic accomplishments, it's almost insulting to point out that former Wonder Years star Danica McKellar is incredibly hot these days. But we're gonna do it anyway.
Christine Taylor got her start in roles like Marcia in The Brady Bunch Movie and Melody in Nickelodeon's Hey Dude. She's still hot, and she's married to Ben Stiller, so we'd say she's doing alright for herself.
Lacey Chabert started out on Party of Five and starred in Mean Girls as one of the Plastics. She famously (and foolishly) abandoned her role as Meg on Family Guy, but hey, at least she's still hot!
Lacey's Family Guy replacement - Mila Kunis - landed the role of Jackie on That '70s Show when she was just 14. Since then she's become one of the hottest and most in-demand actresses in Hollywood.
Christina Applegate started out as Kelly Bundy on Married With Children way back in 1987. Today, at 43, she continues to get hotter with age.
Claire Danes got her big break playing Angela Chase in the critically-acclaimed, but shortlived ABC drama My So-Called Life. These days, she can be seen looking hotter than ever on Showtime's Homeland.
Jennifer Love Hewitt
Like Lacey Chabert, J-Love got her start on Party of Five. And hey, they both grew up to be super hot, too! Winning!
Remember Anna Chlumsy from My Girl. Well, she's in the midst of a career renaissance thanks to her role on Veep. But that's not why she's on this list. No, she's here because she happens to also be super hot!
