This little girl, born into a famous but troubled acting family, won our hearts when she helped a tiny alien find his way home in a 1982 Steven Spielberg film. She was only 6. But the prepubescent actress partied like an adult rock star on the L.A. nightclub scene and was in rehab by age 13, later penning an autobiography, "Little Girl Lost." She has found her way back, has her own production company and is directing her first film with another fresh new face, Ellen Page. Oh, and she's in love with the Mac guy!
