People reports that Lamar has been admitted to a rehabilitation center.
“He realized he needs help,” a source tells the magazine.
Lamar has reportedly been addicted to substances for more than two years and even made a first visit to a rehab center last year.
Last week he was arrested for DUI and his refusal to take a chemical test cost him a one-year suspension of his driver’s license.
Rumors of infidelity and marriage problems with Khloé Kardashian have also been buzzing lately.
