The Kardashian women have their hands full at the moment. While Khloé's husband Lamar Odom remains in a coma from a drug overdose, Kourtney's ex Scott Disick has checked into rehab.

Disick entered a drug rehabilitation center in Malibu, Calif., over the weekend in hopes of winning unsupervised visits with his three children — Mason, 5, Penelope, 3, and Reign, 10 months old, according to TMZ. He's reportedly told friends that Kourtney will not let him have unsupervised visits unless she knows he's clean.

The rehab stint is the second for Disick this year after he visited a center in Costa Rica to use hallucinogenic plants for treatment. He stayed in the program for only one week.

Meanwhile, Odom remains unresponsive at Sunrise Hospital & Medical Center in Las Vegas where emergency services transported him after he was found unconscious at a brothel in Crystal, Nev. Khloé, her sister Kim and mother Kris Jenner have been by his bedside since Tuesday night.

Odom often spent time with Disick and his brother-in-law Rob Kardashian, according to Us Weekly. Rob even lived with him and Khloé for a period of time.
