Scott Disick's recent rehab will allegedly not help in winning Kourtney Kardashian back. According to a report, the beau of the reality star should stop cheating on her.

In a report by The Hollywood Life, Scott Disick, who is in rehab for his alcohol addiction, was given the ultimatum by the "Keeping Up with the Kardashians" star to stop his "womanizing ways."

"Kourtney could take him back if he beats his alcohol demons, but it's not as easy as that," a source dished out. "This time it's a little more personal because he was caught looking flirty with another girl, and she's still embarrassed by that situation. So, it's not entirely about the alcohol problems, there's more to it than that, and she can't forgive him entirely."

Kourtney Kardashian said that aside from Scott Disick's rehab, he should stop being flirty and "behave like a man" if he wanted his family back

"He has to get his act together in more ways than one, by being a reliable partner and father to their three kids and stopping his womanizing ways," the insider concluded.

In previous reports, the "Keeping Up with the Kardashians" beau Scott Disick was photographed canoodling with his 25-year-old ex-girlfriend Chloe Bartoli, and teenager Lindsay Vrckovnik.

The 32-year-old star and 36-year-old Kourtney Kardashian have three kids together.

Meanwhile, the "Keeping Up with the Kardashians" star requested temporary full custody of their kids while Scott Disick is on rehab, a report from In Touch Weekly said.

A source from the website said that if Scott Disick turned sober after his rehab, Kourtney Kardashian will allow him to spend time with their children whenever he wants.

"They love their daddy," the insider said.

Scott Disick is currently facing 30 days of treatment and he was given 90 days to get clean from his addiction.
