Lamar Odom is getting help.
Khloé Kardashian Odom's husband of nearly four years has checked into rehab, less than a week after being arrested on suspicion of driving under the influence, sources tell E! News.
Lamar was arrested at 3:54 a.m. on Friday after California Highway Patrol pulled him over for allegedly driving erratically while heading east on L.A.'s 101 Freeway. He was taken into custody and authorities later said that he refused to take a chemical sobriety test.
