7. Tiger Woods
KNOWN FOR: Playing blackjack at $25,000 a hand.
COMPLEX SAYS: After his multiple affairs got exposed in late 2009, another one of Tiger's vices came to light; gambling. He reportedly has a $1 million limit at the MGM Grand casino and is known for high stakes bets in games like blackjack. Putting up 25 racks a hand when your net worth is $600 million? No biggie. Reportedly going raw dog on jumpoffs (including some porn stars)? Yikes. We're not liking those odds.
