A photo of Justin Bieber and Kourtney Kardashian hooking up has tongues waging, and has gone viral.

The photo which was posted by Justin Bieber on instagram on Sunday, December 13, 2015 that appeared to address his hot new hookups with Kourtney Kardashian, 36, who is a mother of three.

The singer, 21, shared a pic of himself leaning against a black Audi with a woman in what appears to be a compromising position.

"Lord knows," he captioned the shot, which was taken recently based on the fact it shows Bieber's latest neck tattoo Was it a dig at Kardashian's ex Scott Disick who goes by the self-appointed title of Lord?

Chatter of a naked relationship between the stars started in October, with insiders saying Justin and Kourtney, who live near each other in Calabasas, were spending a lot of time together.

Talk then heated up as the romance heated up, as Bieber and Kardashian allegedly danced all night together at Kendall Jenner's birthday party in Los Angeles last month.

“Justin bragged to friends recently that he has been hooking up with Kourtney Kardashian,” an insider tells. While another source adds: “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.”

A website that prides itself on shooting down false rumors says Kourtney left The Montage Beverly Hills Hotel (where Bieber often stays) around 4 a.m. on Saturday mooring, following a night out with Bieber at establishments The Nice Guy and Blind Dragon.

The site quotes a self-proclaimed "impeccable insider" who says Bieber and Kourtney have "hooked up" at least once.

To make things even crazier, a source added that Justin has been totally bragging about his hookups with Kourt.

With his suspicious Instagram pic and caption, it almost seems like he’s trying to brag directly to Scott! It will surely be interesting to see if Scott reacts on his own Insta!
