Scott Disick now knows about Kourtney Kardashian and Justin Bieber’s hookup, and HollywoodLife.com can EXCLUSIVELY reveal how upset he is — and why he thinks she’s a total hypocrite. Ouch!

Scott Disick, 32, has been trying to hard to win back the love of his life, Kourtney Kardashian, 36, but now he’s got major competition. Now that the news is out that she’s been hooking up with 21-year-old Justin Bieber, HollywoodLife.com can EXCLUSIVELY reveal that Scott, the father of Kourtney’s three children, is livid and possibly even planning some retaliation.

The shocking news that Kourtney and longtime Kardashian friend Justin Bieber are hooking uphas everyone shocked, but no one more than her ex, Scott. Even though the former couple seemed to be rekindling their relationship while spending time together with their children, it seems Scott now knows it’s going to be a lot harder than he thought — especially since Kourtney is a little preoccupied with her new fling.

“Scott is trying to get better, trying to turn a new leaf and now Kourtney is going out late night and hooking up with another bad boy in Justin,” a source close to him tells HollywoodLife.comEXCLUSIVELY, revealing Scott’s frustration with the situation. “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.” As HollywoodLife.com previously reported, Scott believes that Kourtney is “testing” him so that she doesn’t get hurt again… and this might just be one of those tests.

But, it doesn’t end there. Adding to Scott’s shock and frustration is the fact that “he really feels that Kourtney is very hypocritical.” The source continued by sharing, “[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.”
