Justin Bieber And Kourtney Kardashian 'Hooking Up?' Scott Disick Release Statement?

Justin Bieber posted a photo on Instagram that fueled up dating rumors with Kourtney Kardashian. The "What Do you Mean" singer was boasting to his friends that he's "hooking up" with Scott Disick's ex-partner.

The image was allegedly new based on the singer's recent neck tattoo. In the photo, he was facing a woman dressed in black in a position where her face was covered with his body. The lady was sitting on an Audi car's hood and it was captioned, "Lord knows," according to Mirror.co.uk.

Justin Bieber and Kourtney Kardashian were spotted together on Dec. 11 at the Nice Guy in L.A. A source revealed that the 36-year-old star was last seen at Montage Beverly Hills hotel where the singer stayed and left at 4 a.m. They also dined together in October at the same place before they went to Universal Studios Halloween Horror Nights, according to Us Weekly.

Scott Disick has been trying to win the reality star back, sources said. The former couple recently spent time together with their kids in an effort to fix their relationship. However, the new revelation seemed to have shocked him.

A source close to Disick revealed, "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," according to Hollywood Life.

"So, Scott feels like it is a slap to the face," the statement continued. "He feels that he is doing what she wants and she is now doing things just to make him feel bad." 

He believed that this flame with Justin Bieber was allegedly one of Kourtney Kardashian's challenge to him to prove that she'll never get hurt again. However, Scott Disick was frustrated about what happened and wanted to make a revenge to his ex whom he allegedly called "hypocrite."

With regard to the issue, neither the reality stars nor the 21-year-old singer has released any statements.
