Mamie Gummer, the second child of Meryl Streep and husband Don Gummer, first appeared alongside her mother in "Heartburn." She went uncredited in the film to avoid media scrutiny. Mamie, 30, 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 starred in the now-canceled CW series "Emily Owens, M.D.," and will appear in the 2015 Jennifer Aniston movie "Cake." —XFINITY Entertainment Staff (AP Photo/Diane Bondareff)
