Mary-Kate Olsen’s (born June 13, 1986) breakout role was on the show "Full House" when she was just nine months old. Due to strict child labor laws, she and her fraternal twin sister, Ashley Fuller Olsen, shared the role Michelle Tanner. After "Full House," Mary-Kate went on to star in numerous television programs and films as well as endorse a seemingly endless string of commercial products. She was also the first person called upon the discovery of Heath Ledger’s body, raising some questions about her knowledge of the actor’s sudden death.
