Scott Disick Is All Smiles Dining With Kris Jenner After Rehab

Scott Disick appears to be feeling great post-rehab.

Rehab already appears to have done Scott Disick a lot of good.

The 32-year-old reality star was spotted going out for a sushi dinner with Kris Jenner and a friend at Nobu in Malibu, California, on Thursday night. ET exclusively reported that Scott checked out of rehab on Wednesday, after a month-long stint at a Malibu treatment center.

Clad in a simple hoodie and jeans, Scott appeared to be in pretty good spirits, and also looked healthier and happier than he has in recent months.

Scott and Kris arrived at around 8:20 p.m. and stayed for roughly two hours, leaving in separate cars at around 10:30 p.m., an eyewitness tells ET. The two were very talkative toward each other, smiling as they said goodbye after catching up.

Kris has clearly been a supporter of Scott throughout the past month. The 60-year-old momager, as well as Scott's three kids with Kourtney Kardashian -- 5-year-old Mason, 3-year-old Penelope and 10-month-old Reign -- were spotted visiting him in rehab on Oct. 25.

"The entire Kardashian family is supporting him throughout this, including Kourtney," a source close to Scott told ET on Thursday. "He is doing really well. Everyone is hoping that his sobriety continues but he is looking great and feeling great."

Scott is continuing to receive out-patient treatment to maintain his sobriety, the source adds.

Scott's latest stint in rehab -- his fourth known attempt in a year -- can already be considered a success in one aspect. It is believed to be his longest stay ever.

"Scott is family, too," Kim said. "He'll always be in our lives so we want the best for him. He’s getting help and he’s been doing so good and that makes me happy too."
