Kourtney Kardashian is reportedly hooking up with Justin Bieber.

It's no secret that Kourtney Kardashian has a thing for younger men. But hopes of her getting back together with baby daddy Scott Disick seem less likely these days. She's found a new, even younger guy: Justin Bieber.

According to US Weekly, "Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian." She even attended his American Music Awards after-party on Sunday, Nov. 22.

A second insider shared, "Oh yeah, that's definitely happening and has been for some time now. Every time Kourtney and Justin are together they're extremely flirtatious. They text each other all the time."

The couple, who have a 15-year age gap, spent Friday night together, starting at Hollywood hot spot The Nice Guy and then going to karaoke lounge Blind Dragon.

An eagle-eyed eyewitness at The Nice Guy told US Weekly, "Kourtney and Justin seemed flirty. I saw them a few times touching and laughing together."

TMZ reported Kardashian left The Montage, a hotel in Beverly Hills where Bieber usually stays, at 4 a.m. on Saturday, Dec. 12.

It seems that their relationship has been going on since October, when the duo had dinner at The Nice Guy (they seem to really like this spot) and then hit up Universal Studios for the "Halloween Horror Nights" attraction.

While enjoying the rides, an eyewitness shared, "When he was there with Kourtney, he was such a gentleman and so nice and respectful. He was definitely trying to impress Kourtney and act more mature."

Surprisingly, the couple have quite a few ties. Bieber is a longtime friend of the Kardashian-Jenner clan and his former tour manager and close friend, Corey Gamble, is currently dating Kourtney's mom, Kris Jenner. Bieber is friends with Kendall Jenner and has even babysat for Kourtney's three kids. No word on whether sparks flew over diaper changes.
