“He’s been eating clean, exercising and looking after the kids," a source said. "And most importantly, he’s three or four weeks sober now.”

“Scott’s the first to admit he put Kourtney and the kids through hell and he doesn’t probably deserve any sympathy, let alone a reunion," the source added. "But he’s giving it a try and wants to prove that he’s capable of being a better person, for the kids as much as himself."

Kourtney previously admitted her split with the 33-year-old took a toll on her mental health, causing her to suffer from anxiety. She and Scott split last year after he was caught partying with an ex-girlfriend. The former couple share kids Mason, 6, Penelope, 4, and Reign, 1.
