Scott Disick is doing well as he prepares to celebrate his 33rd birthday Thursday.

“He seems like he’s in a really good place,” a source tells PEOPLE. “He’s single for the first time in a long time, so of course he’s having fun. He’s going out and talking to people, but he also loves his kids and is making them a priority. He’s pretty upbeat and seems content with life.”

Disick, who split from Kourtney Kardashian in July 2015, entered rehab in October. The source says during recent outings, Disick has kept his partying under control.

“He’s usually just sitting and chilling, sipping on a couple drinks. He’s not crazy,” says the source.

Disick was recently spotted partying in Cannes with his ex’s sister Kendall Jenner and mother Kris Jenner.

Ahead of his birthday celebrations, Disick shared a throwback photo to his Men’s Fitness cover from 2011, captioning it, “The good ole days.”

He also tweeted that he’d be celebrating his birthday with a bash at The Pool After Dark in Atlantic City, New Jersey on Saturday, two days after his actual birthday.
