Charlie Sheen

Biography: With Martin Sheen for a father, it's not surprising that Charlie Sheen became a film and TV star. Yet this bad-boy actor is even more famous for his off-screen antics. Although he made a splash in a succession of '80s blockbusters (Wall Street, Young Guns, Platoon), Sheen also struggled with drinking and drug use. After being relegated to parts in B-movies (The Chase, Money Talks) in the '90s, Sheen made a professional and personal comeback in the new millennium by joining the cast of Spin City and marrying bombshell Denise Richards. While his TV success continued with a starring role in the sitcom Two and a Half Men, which snagged Sheen his first Emmy nod, his real life faltered when Richards left him in 2005 while pregnant with their second child. Following their divorce in 2006, Sheen married real-estate agent Brooke Mueller, with whom he has twin sons. The couple made headlines in 2009 following an alleged domestic incident on Christmas Day in Aspen, Colorado.
