Since his split from Courteney Cox earlier this year, David's been a hot mess. Whether he's hitting on random reporters, jumping through windows to reach the bar or staying at clubs until closing, David's partying the pain away. In the New Year, he's opening a Hollywood club complete with dancing little people, but he tells his therapist Howard Stern he's trying to quit boozing so much. (One of his first acts of 2011? Entering rehab.) Good luck, David!
