Mamie Gummer, the second child of Meryl Streep and husband Don Gummer, first appeared alongside her mother in "Heartburn" at the age of 2. She went uncredited in the film to avoid media scrutiny. Mamie, 32, made her Broadway debut in 2005 alongside Michael C. Hall in "Mr. Marmalade." She has since had several small roles in film and television and appeared in "The Good Wife" and "The Big C." She recently appeared in her mom's film "Ricki and the Flash." —XFINITY Entertainment Staff (Photo: Evan Agostini/Invision/AP)
