Scott Disick was spotted for the first time on Thursday at a drug and alcohol rehab center in Malibu, California where he is receiving treatment.

The 32-year-old reality star checked in for treatment on Wednesday, a source told ET. Photographers spotted him outside the center, looking casual in a hooded sweatshirt and sporting a beard.

He checked into the center just one day after posting a cryptic Instagram photo of the words "Never give up" written in chalk.

Disick has been having a tough year, as he and longtime love Kourtney Kardashian called it quits in July after he was photographed cozying up to an ex-girlfriend in Monte Carlo. "I made the worst decision I've ever made in my life," he told Kardashian in a recent episode of the family’s reality series, Keeping Up With the Kardashians.

Then earlier this month, Disick was seen out and about in New York City and Miami with 18-year-old model Lindsay Vrckovnik.

While Kardashian and Disick share three young children, a source recently told ET not to expect a rekindled romance anytime soon.

"Kourtney is not taking Scott back -- never, as of right now," the source said. "Kourtney has been through a lot of drama with Scott over the years but it's for real this time."
