Anyone who remotely follows “Keeping Up With the Kardashians” knows that Scott Disick loves to get paid to party. But after his split with longtime girlfriend Kourtney Kardashian, the self-proclaimed lord canceled his appearance at the Las Vegas nightclub, celebrity blogger Perez Hilton reported Thursday night.

Disick, who has struggled with substance abuse in the past, was reportedly pressured by friends to seek therapy once again. He supposedly entered rehab on the same day his girlfriend of nearly a decade broke up with him but left hours later.

The father of three even missed his daughter Penelope’s third birthday, but he managed to send her a message via Instagram, as self-deprecating as it may have been. “1 of the only things I'm proud off about myself. Happybdayp,” he wrote to Penelope. He also shares two sons with Kardashian: Mason Dash and Reign.

Kardashian, 36, reportedly broke things off with the father of her children after she saw paparazzi photos of Disick, 32, getting cozy with ex-girlfriend Chloe Bartoli in Monaco over the Fourth of July weekend.

Now that he’s not with Kardashian, the New York native is reportedly thinking about writing a tell-all book about the family. “Scott’s considering writing a tell-all book about what it has been like to be part of reality TV’s most famous family. He’ll definitely offend a lot of the family if he does,” an insider told Hollywood Life. “This is something he’s talked about, even before the split, and Kourtney has already warned him to not even think about it.”

Disick and Kardashian had not issued a statement about their breakup at the time this story was reported. For all the latest Kardashian drama, check out “Keeping Up With the Kardashians" on E! every Sunday at 9 p.m. EDT.
