Kourtney Kardashian Hooking Up With Justin Bieber to Get Back At Scott Disick? [VIDEO]

Kourtney Kardashian split from her troubled baby-daddy, Scott Disick, earlier this year after 10 years together. Now it's being reported the reality star is hooking up with Justin Bieber! Kardashian was spotted getting close to the 21-year-old pop star, who later appeared to throw shade at Disick with an Instagram post.

The 36-year-old reality star was spotted partying at The Nice Guy in West Hollywood, where Kourtney watched Justin perform.

Page Six's source revealed, "They were smoking on the patio together and were super touchy-feely."

Kardashian and Bieber reportedly continued hanging out at Blind Dragon, but left at separate times.

An insider revealed they later met up at Bieber's hotel room at the Mondrian and Kardashian was seen leaving at around 4 a.m.

Bieber later posted a photo of himself with a mystery woman sitting on the hood of an Audi, with the caption "Lord Knows."

Anyone that has tuned in to "Keeping Up with the Kardashians" knows that Disick refers to himself as "Lord Disick."

There are reports by US magazine that the pop star has been telling friends that he is banging the 36-year-old reality star.

Kardashian was in attendance at Bieber's American Music Awards afterparty at the Nice Guy in late November in Los Angeles.

A source said of the hook-up rumors, "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."

Kardashian is the mother of three children with Disick. The reality star has son Mason, daughter Penelope, and son Reign with Scott Disick.

Page Six reports that Kardashian is giving Disick a little payback by hooking up with The Biebs.

Their source reveals, "Scott hates it that Bieber is the younger, hotter and richer version of him — in his eyes — and seeing him with Kourtney pisses him off even more. Kourtney knows it upsets him, so when Scott flaunts being out with other girls, she hangs out with Justin to get back at him."
