The Olsen Twins

Twin actresses Mary-Kate, left, and Ashley Olsen pose for a photo April 18, 2004, in Los Angeles. The sisters, who have been famous since they were 9 months old, own a billion-dollar enterprise of direct-to-video movies, a fashion line, and assorted books, dolls, trinkets and doodads. Their feature film, "New York Minute," opened May 7, 2004.

Starting as 9-month-old infants, the Olsens played the character of Michelle on ABC's "Full House" sitcom - a role they shared for nine years. Pictured here are the "Full House" cast: (front) Jodie Sweetin, Bob Saget, Mary-Kate Olsen, Candace Cameron, (back) Dave Coulier, Lori Loughlin and John Stamos.
