Justin Bieber posted a photo on Instagram on Sunday, December 13, that appeared to address his hot new hookups with Kourtney Kardashian.

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 that 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?

As Us Weekly exclusively reported on Sunday, the "What Do You Mean?" singer has "bragged to friends recently that he has been hooking up with Kourtney Kardashian," according to an insider.

Selena Gomez's ex and the mother of three were spotted together at the Nice Guy in L.A. on Friday, December 11, where an eyewitness told Us they "seemed flirty."

And according to TMZ, the Keeping Up With the Kardashians star, 36, who split from Disick, 32, in July, later went to the Beverly Hills hotel the Montage, where Bieber often stays, and she didn't leave until 4 a.m.

The pair also met up in October for dinner at Nice Guy before stopping by Universal Studios' Halloween Horror Nights attraction, and the insider told Us that Kardashian was also at Bieber's American Music Awards afterparty at Nice Guy on November 22. See photos from their night out.

"Every time Kourtney and Justin are together they're extremely flirtatious," a second source told Us. "They text each other all the time."
