Lamar Odom has checked himself into a drug and alcohol rehabilitation center, PEOPLE confirms.
"He realized he needs help," a source says of the NBA free agent and husband of reality star Khloé Kardashian Odom.
Odom's drug use had been causing trouble in the couple's marriage, though Kardashian has been focused on getting her husband help.
Late last week, Odom was arrested for DUI.
The basketball player, 32, has admitted to drug use in the past. He violated NBA drug policies twice in eight months back in 2001, and spoke in 2003 of his marijuana use. "I just couldn't control myself in L.A. ... the lifestyle that I was living and the things I had access to," he said.
Hope it helps
