You Know Her As… Stephanie Tanner, the smart-aleck middle sister to D.J. (Candace Cameron Bure) and Michelle (Mary Kate and Ashley Olsen) on Full House (1987-1995).
Where Is She Now? Sweetin, 29, had a tough road after the show ended. In her 2009 memoir unSweetined, the actress described her years of drug addiction -- including such lows as snorting meth at the premiere of the Olsen twins' New York Minute. Sweetin is now a sober mother of two young daughters, Zoie, 3 (from her first marriage to Cody Herpin), and (pictured) 8-month-old Beatrix (whose dad is Sweetin's musician boyfriend, Morty Coyle). "(My struggles are) pretty much in the past," she said in April 2011. "Hopefully, it'll never be anything my kids have to be a part of."
