Scott Disick is rumored to be going through withdrawal symptoms and crying out for ex Kourtney Kardashian while in rehab.

According to Radar Online, Disick is so desperate for contact with Kardashian, he's taken to bending facility rules forbidding patients from having contact with anyone outside the establishment. He has reportedly been reaching out to his ex-girlfriend and the mother of his three young children nonstop.

"Scott has been calling Kourtney from rehab," a source said. "The last time he phoned her, he was really upset and emotional."

Word is that conversation peaked with Disick begging his ex to give him one more chance, a plea to which she's yet to offer a definite answer. Kardashian informed him she wouldn't be taking any more of his phone calls in the immediate future in order to give him the time he needs to clear his head and focus on his sobriety.

"Kourtney only did it to begin with because she knew Scott was going through the beginning period of rehab and wanted to know about what was going on with Lamar [Odom]," a source added. "Scott's been really worried about him and asking a lot of questions. He thought he was dead."

After nine years and three children together, Disick and Kardashian called it quits earlier this summer, when he was spied cavorting with ex-girlfriend Chloe Bartoli in Monaco over the July Fourth holiday weekend. Since then, he's also been romantically linked to 18-yer-old model Lindsay Vrckovnik.

But now with his career and maybe even his life on the line, Disick only seems able to think of Kardashian and his family.

"There's no chance Kourtney will be with him until she sees continued positive actions from Scott during his recovery," a source said. "He always said one thing and did another before and she fell for it so many times -- but not this time."
