Disick, who turned 37 on Tuesday, joined Khloé Kardashian, Kylie Jenner, Kourtney Kardashian, Kim Kardashian and all of their kids for a splashy birthday party that included a moon bounce, an ice cream cart and T-shirts from Disick’s brand, Talentless, that read “Disick Quarantine Club” on the back. Khloé’s 2-year-old daughter, True Thompson, was photographed modeling the tee.

The “Flip It Like Disick” host also showed off the “most over the top” mountain bike he received from Kris Jenner.

The party took place after Disick jetted to the luxurious Amangiri resort over the holiday weekend with ex-girlfriend Kourtney and their three kids: 10-year-old Mason, 7-year-old Penelope and 5-year-old Reign.

Disick’s now-ex-girlfriend, Sofia Richie, hasn’t been involved in any of the gatherings.

As Page Six exclusively reported, Disick and Richie broke up after nearly three years together.

“Scott had gone back to his old ways,” our source told us, “and Sofia got fed up.”

In April, Disick checked in-and-out of rehab to treat his “past traumas” stemming from the deaths of his parents.

His close relationship with Kourtney also took a toll on their romance, we’re told.
