Scott Disick is still on the road to recovery but took a break from a rehabilitation center to hang out with Kourtney Kardashian over the weekend. The pair, who split in July after 10 years of dating, was spotted at a house party in California's Malibu to support celebrity Pastor Rich Wilkerson Jr.'s new book.

In a video posted by TMZ, Disick and Kardashian are seen standing near each other at the star-studded party Friday night. The outlet pointed out that Disick, who's in rehab for alcohol and drug addiction, appeared "totally tame" at the get-together.

The former couple's outing marked the first time Disick and Kardashian have been publicly spotted together since their breakup.

According to People magazine, the mother of three and Disick are working on their relationship. A source told the outlet that the "Keeping Up With the Kardashians" star is "starting to trust [Disick] more," but the two have not discussed getting back together.

"Scott is doing well and seems very happy,” the source said. “He is committed to staying sober. He is happy to get his life back in order and is focused on being the best dad for the kids.”

Shortly before Disick, 32, and Kardashian, 36, had their night out, the businessman was spotted grabbing dinner with Kris Jenner at the Japanese restaurant Nobu in Malibu.

According to E Online, he's allowed to leave the rehab center for different activities and to visit his children. Disick checked into Cliffside Malibu in October, shortly after Khloe Kardashian's estranged husband Lamar Odom was rushed to a Las Vegas hospital after being found unconscious inside a legal brothel in Nevada.
