Scott Disick has the support of his children -- and even Kris Jenner -- as he continues his stay at a rehab center in Malibu, California.

The 32-year-old reality star was photographed at the rehabilitation center on Sunday, when he got a visit from his three children -- 5-year-old Mason, 3-year-old Penelope and 10-month-old Reign -- as well as 59-year-old Kris. Scott was also photographed giving a few male friends a hug.

Scott was affectionate with his kids, giving baby Reign a kiss on the head, as well as picking up both Penelope and Mason. He also posed for family photos with Kris, who had a big smile on her face, and was still wearing the same pajamas she sported at Kim Kardashian's camp-themed baby shower earlier in the day. An eyewitness tells ET that the visit lasted two hours, and that Scott "seemed fine, but a bit serious" around Kris.

Noticeably absent from the family visit was Scott's ex, 36-year-old Kourtney Kardashian. The mother of three has been adamant about not keeping their children away from their father, a source told ET in September, despite the status of their own relationship. "Scott sees the kids whenever he wants to," the source said. "Despite all of Scott's addiction problems, he is a great dad and loves those kids with all his heart, and they are obsessed with him."

Scott has been in rehab for more than a week now, a source told ET on Thursday, which is believed to be his longest stint in rehab ever. His latest stay is actually Scott's fourth known attempt in a year -- previously, his longest stint was believed to be at the Rythmia Life Advancement Center in Costa Rica in March, where he stayed for one week. Scott also checked into rehab on July 5 in Florida, according to Us Weekly, and he left Connecticut's Mountainside Treatment Center after just five days in a November 2014 episode of Kourtney & Khloe Take the Hamptons.

Meanwhile, Kourtney was spotted having dinner with Scott's friend, Chris Reda, on Sunday night. Reda is one of the friends who was photographed visiting Scott in rehab earlier that day, so presumably, he gave an update on Scott's condition to his estranged ex.

In a recent preview for the upcoming season 11 of Keeping Up With the Kardashians, Scott admits he's been having a hard time dealing with his breakup with Kourtney.

"It's been a really hard time, going from like, having all of you guys to having nobody," he tells Kris, Kourtney, and Khloe, as he breaks down in tears.

After Kourtney tells her ex, "You forget what happens when you're on a binge," he confesses, "I f**ked up. I made the worst decision I've ever made in my life."
