Not only is she gorgeous, hilarious and down to Earth - Christina Applegate looks damn good for turning the big 40 today! Best known for playing Kelly Bundy, the dumb blonde, on the FOX sitcom Married...with Children, Christina has surpassed any stereotype she may have earned from that role and turned her career into a very successful one. Growing up in Hollywood with a producer father and an actress mother definitely helped out her career but Christina made a name for herself, independent from her parents. Although she did make her television debut with her mother on Days of Our Lives, her career took off after that and kept on rising even to this day.
