It’s definitely happening! Kourtney Kardashian and Justin Bieber are hooking up, sources confirm to Us Weekly.

“Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian,” an insider tells Us, adding Kardashian was at Bieber's American Music Awards afterparty at the Nice Guy in L.A. on Sunday, November 22.

“Oh, yeah, that’s definitely happening and has been for some time now,” adds a second source. “Every time Kourtney and Justin are together they’re extremely flirtatious. They text each other all the time.”

The 21-year-old pop singer and the Keeping Up With the Kardashians star, 36, spent Friday night together out in L.A., hitting up Hollywood hot spot the Nice Guy and then later heading to karaoke lounge Blind Dragon. Click here to see more pics from their night out. 

“Kourtney and Justin seemed flirty,” an eyewitness at Nice Guy told Us. “I saw them a few times touching and laughing together.”


TMZ reported that the mom of three — who split from ex Scott Disick in July — went to the Beverly Hills hotel the Montage, where the “Sorry” singer often stays, and checked out at 4 a.m.

Back in October, Selena Gomez’s ex and Kardashian had dinner together at the Nice Guy and then stopped by Universal Studios for the “Halloween Horror Nights" attraction.

“When he was there with Kourtney, he was such a gentleman and so nice and respectful,” a source told Us. “He was definitely trying to impress Kourtney and act more mature.”

Another source also told Us that Bieber purchased their tickets.

Bieber is a longtime close friend of the Kardashian-Jenner clan, and has been photographed babysitting Kardashian’s three kids — Mason, 5, Penelope, 4, and Reign, 11 months. His former tour manager and close friend Corey Gamble is currently dating Kourtney’s mom, Kris Jenner, and earlier this year, Bieber snapped a goofy selfie with Kardashian’s younger half-sis, model Kendall Jenner.
