Actresses Who Make Watching Their Younger Work Uncomfortable (NSFW)

Alyssa Milano's growth into a beautiful woman didn't take people by surprise as much of her teen years were spent on the show 'Who's the Boss?'  But after her run as the the daughter of Tony Danza, Milano took on some more adult-orientented roles, like 'Embrace of the Vampire' where she stripped down and got frisky with another lady.  Then her years as the bra-less witch on 'Charmed' made us all try to forget that she was once Arnold's little girl in 'Commando'.

Alexa PenaVega's transformation as an innocent young spy to a sexy lady came as a bit of an abrupt surprise to those who those who saw her in the 'Spy Kids' series.  With the 'Spy Kids' films she latched on to director Robert Rodriguez, who then had her sport underwear, chaps, and a machine gun as the badass prostitute in KillJoy for 'Machete Kills'.  If there's any chance you'll watch the original 'Spy Kids' movies again, think you'll be able to get that image out of your head?

Chloe Grace Moretz is unique for this list.  Sure, she's grown to be a gorgeous woman, but the likely-hood of you going back and watching her early work in 'Big Momma's House 2' is slim.  Nevertheless, its hard to look at that sweet little girl and think of her being soaked in blood as the homicidal Carrie or dropping F and C-bombs as Hit Girl in 'Kick Ass'.

Shawna Waldron is one of the bigger shocks on this list since she went from young female football player straight to D-list softcore porn star in the eyes of many audiences.  Waldron got everyone's attention as Icebox in the family-friendly favorite 'Little Giants', and followed it up the next year as the President's daughter in 'The American President'.  After that, Waldron fell out of the public eye, still acting but never getting the wide-spread attention her first two jobs got her.  And then in 2008 she starred in the film 'Poison Ivy: The Secret Society', a made-for-cable skinflick where the former child star sports a bikini, and less, in a soft-core romp.

Here's a maturing that we saw coming as Danielle Fishel grew up on the show 'Boy Meets World'.  We knew then she was growing into a very attractive woman, but was out of the public eye for a bit, during which time she transformed into pure knockout.  Normally, 'Boy Meets World' isn't something you'd stumble across on TV, but with the popularity of its spin-off series, 'Girl Meets World', the days of Corey and Topanga are relevant again and we are exposed to younger days of a girl who'd grow up to be Disney's number one MILF.

Stewart is another one on this list who is here not for her looks, which are definitely noteworthy, but more about what she's been doing as of late.  Going from the somewhat ambiguously gendered daughter of Jodie Foster in 'Panic Room', we have to watch that movie and remember that this young girl will later star in some of the most critically despised films of all time, and then strip down to nothing and give the hand jive to two guys in the front seat of a car in 'On the Road'.

Here we have the perfect example of young girl growing into total bombshell.  Once Lacey Chabert grew up, she did what she could to shed her image from 'Party of Five' without going too far like other former child stars.  Sure, she's posed for Maxim a few times and sports her body when she can, but she's yet to pose nude in print or film.  Not to say she hasn't gone dirty from time to time, like her bit part in 'Not Another Teen Movie'.  And while it may creep you out to watch old episodes of 'Party of Five' and think of how she looks today, the bigger problem is that you're spending your free time watching old episodes of 'Party of Five'.

From Harriet the Spy to Buffy's magical little sister to holy crap!  Sure, you may not be likely to pop in something like 'Harriet the Spy' or 'Inspector Gadget' to pass the time on a dull weekend, but 'Buffy the Vampire Slayer' is still a geek favorite and popular on Netflix.  But if her family friendly work is something you still enjoy, be sure to avoid her work in the highly underrated film 'Eurotrip'.  That's a connection you don't want to make.

And here we go, the prime example of how bad parents can screw up a child.  Once a cute and innocent child star who looked to be bridging the gap to beautiful leading lady.  Unfortunately, she got caught up in the wild Hollywood lifestyle and turned into the skank who has been with so many guys she could probably give you a STD just by sneezing in your general direction.  She channeled Marilyn Monroe in a pictorial for Playboy, and has recently bared all in a sex scene with an adult film star in 'The Canyons', making her days as the cute little redheaded girl in 'The Parent Trap' seem like someone else's life.

Winnie Cooper was the first television crush for how many children of the late 80s?  Many viewers went from seeing Danica perform Winnie's first kiss on 'The Wonder Years' to rockin' some abs on 'Dancing with the Stars'.  McKellar's beauty is matched by her brains, being fluent in French and a respected mathametician, releasing a set of books designed to get young girls interested in math.  Pretty sure girls won't be the only ones interested in what she has to say.

Yeah...
