Lamar Odom has checked himself into rehab.
A source tells People magazine, "He realized he needs help." Lamar's troubles with drug and alcohol were revealed last month, and have been causing trouble in his marriage to Khloe Kardashian, who reportedly threw him out of their home until he cleaned himself up.
Last week, the NBA star was arrested for DUI.
According to People magazine, Lamar violated NBA drug policies twice in eight months back in 2001 and admitted to smoking pot in 2003. "I just couldn't control myself in L.A.," he said at the time. "The lifestyle that I was living and the things I had access to."
