Mary-Kate Olsen (born June 13, 1986) is an American actress, producer, author and fashion designer. She made her career debut in 1987, alongside her twin sister Ashley, in the television series "Full House". Following that success, Mary-Kate with Ashley starred in television and film roles that saw her become an international household name.
Since 2006, Mary-Kate has been pursuing acting roles independent of her sister. Her sometimes controversial fashion choices have often found her on both the best and worst dressed fashion lists, particularly for her decision to wear fur.
