10. Christina Applegate
Christina Applegate has been enjoying a career resurgence of late, with all the success of Anchorman, her work on Broadway (she was nominated for a Tony for her performance in the 2005 revival of Sweet Charity), and her more recent television shows (Samantha Who and Up All Night). So much so that a lot of younger viewers might not even know about the work she did in the 80s and 90s, back when she was best-known for her portrayal of Kelly Bundy on Married With Children. If you're just getting acquainted with her now, you probably look at her and think that she's a beautiful woman. But if you know exactly how long she's been in Hollywood looking that good, you would be even more awed. Honestly, when I look at pictures from Married With Children and compare them to what Christina Applegate looks like now, the only real change I notice is the disappearance of the tremendously awful early 90s clothing. Other than that, she looks enviably similar to her 20-something self. Given the health issues she's had in the past, I'm incredibly impressed by her commitment to maintaining a healthy lifestyle.
