America watched as Michelle Tanner teetered from a toddler to a rambunctious 8-year-old, and as she did so, so did dynamic duo Mary Kate and Ashley Olsen. The twins turned their "Full House" fling into a full-fledged franchise, and turned their company, Dualstar, into a multibillion-dollar operation. Finally legal, the infamous twins have come a long way from diapers, and are now known for their iconic fashion statements and Hollywood appearances. But growing up in the public eye is never easy, and Mary Kate has battled rumors of drug abuse and anorexia. She also recently began a recurring appearance in her first solo (minus Ashley) role in the Showtime indie hit "Weeds."
