Lamar Odom's troubles have apparently reached the tipping point. He reportedly entered a drug and alcohol rehabilitation center on Wednesday for an alleged crack addiction, about a week after getting arrested for DUI.

"People" mag says the athlete "realized he needs help."

Khloe Kardashian reportedly gave Odom an ultimatum, telling him he could go to rehab or get out of the house. Though he didn't go at the time, Odom evidently changed his mind.
