Sources have confirmed that Kourtney Kardashian and Canadian superstar Justin Bieber are dating.
However, Kourtney's ex husband seems not amused with the news, according to Hollywood Life.
"Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian," according to a source who told US Weekly.
In addition, the source told the publicatin that Kardashian was at his American Music Awards after party at the Nice Guy in Los Angeles on Nov. 22, Sunday.
Another source also told US Weekly that the Justin Bieber - Kourtney Kardashian pairing is totally happening.
"Oh yeah, that's definitely happening and has been for some time now," said the source. "Every time Kourtney and Justin are together they're extremely flirtatious. They text each other all the time."
"When he was there with Kourtney, he was such a gentleman and so nice and respectful," another source told Us Weekly. "He was definitely trying to impress Kourtney and act more mature."
Whether or not the new dating pair is official, Kourtney Kardashian's ex-husband Scott Dissick did not accept this news so well.
The father of Kourtney's three kids was more shocked than the wholr Kardashian-Jenner family.
"Scott is trying to get better, trying to turn a new leaf and now Kourtney Kardashian is going out late night and hooking up with another bad boy in Justin Bieber," a source told Hollywood Life. "So, Scott feels like it is a slap to the face. He feels that he is doing what she wants and she is now doing things just to make him feel bad."
However, what's more shocking and frustrating for Scott is the fact that "he really feels that Kourtney [Kardashian] is very hypocritical [with the whole Justin Bieber news].
"The source added, "[Scott] is thinking of retaliation and may join her in hurting each other and he now has a complete different outlook on how he is going to treat that night."
