Kris Jenner is speaking out against claims Rob Kardashian has checked into rehab.

A South Florida-based blog called Gossip Extra reported Thursday that Kardashian had checked into a drug and alcohol rehab center in Palm Beach over the weekend for a 60-day treatment. The blog’s source was Mark Behar, a celebrity bodyguard who allegedly knows the reality star.

Jenner slammed the rumor, telling ET Friday that the story is “completely fabricated.” She also spoke to E! News, calling it “false” and adding: “Rob is not in rehab.”

Neither Kardashian nor a rep for the family was immediately available for comment. He did, however, post a tweet Friday afternoon.

Yo yo yo,,, we gonna get that puck on the ice tonight and do a little pass , shoot , and score‼️

The 28-year-old has remained out of the spotlight for the past year, famously skipping sister Kim’s wedding to Kanye West last May. Last month, Khloe said her brother is “struggling” during a red carpet interview, but is working to get better.

“Rob definitely has his ups and downs, and he’s been struggling for the past year and a half, maybe two years, which I think we’ve all had those times in our life,” she said. “For the last week, he’s been doing better, but I want Rob to do good consistently forever. So right now I’m really proud of him. He’s been working out a little and trying to get his groove back. And he acknowledges it — he’s aware that he’s very introverted and of course not the way he used to be.”
