Lord knows? Scott Disick is apparently already aware of Justin Bieber-Kourtney Kardashian hooking up reports. He's reportedly devastated and thinks that the mother of his kids is a hypocrite. It seems things are heating up with Bieber's controversial social media post which seemed to throw major digs to Lord Disick.

On Sunday, Bieber shared a creepy Instagram post that seems to hint something about the latest rumors about him and Kardashian. In the photo, the 21-year-old "Sorry" hitmaker is seen leaning against an Audi car with an unidentified woman in a provocative position, Us Weekly reports. The photo was captioned with "Lord knows." It instantly made rounds on the Internet with many wondering if the Canadian singer was dissing Kardahsian's ex-boyfriend as everyone knows that the reality star prefers to be called Lord Disick.

Disick is reportedly hurt about the shocking news. "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 Disick told HollywoodLife. "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."

Ever since Kourtney and Bieber's romance rumors started, it has been rocking up the tabloids. Disick is definitely upset about the whole situation, hearing about new reports about his ex-girlfriend having a fling with the young popular singer. Selena Gomez's ex and the 36-year-old TV personality were seen a couple of times together, triggering more controversies that there's something going on between the two.

"He and Kourtney were nearly inseparable - smoking on the patio together and were super touchy feely," a source revealed to PEOPLE.

New reports reveal that Bieber-Kardashian's hook-ups are not new. It was said that their affair began in October following their flirty hangouts at Nice Guy in West Hollywood. The two reportedly made out many times, with some sources claiming there's nothing bad about it because both of them are single. The new development will surely hurt Lord Disick more. It is said that he's now considering retaliating against her since all his efforts to win her back failed.
