Lord knows

Show yourself! The mystery girl in Justin Bieber's racy Instagram post from Sunday, December 13, has finally been revealed — and it's not the pop superstar's hookup Kourtney Kardashian.

Bieber, 21, posted a pic to his Instagram of a woman in a compromising position, bent over a black Audi with only her legs on display. "Lord knows," Bieber captioned the racy snap, seemingly alluding to Scott Disick, who refers to himself as "Lord Disick."

While the woman's face remained concealed  many believed it to be Kardashian  x17 online revealed on Monday, December 14, that it wasn't the reality star and mom of three. In fact, the girl in Bieber's picture was a pretty blonde who spent the vast majority of her Sunday with the "Sorry" singer in Newport Beach, California. She and Bieber even chartered a yacht with a group of pals as the sun set over the Pacific. The woman's identity has yet to be revealed.

That crazy photo, meanwhile, was taken by an unidentified Bieber pal, who was himself snapped shooting the two with an iPhone by the side of the road.

Bieber has come off an eventful weekend, after spending part of it with Kardashian at West Hollywood hot spot The Nice Guy, where they appeared to be “flirty," according to one onlooker.

That night, Kardashian showed up at The Montage, where Bieber frequently stays, and didn't leave the Beverly Hills hotel until 4 a.m.

Bieber is still very much single, he told Us Weekly last month. "I like a beautiful girl. Who doesn’t?" he said, adding that he wasn't ready to settle down anytime soon. "I’m not really ready to date right now," Bieber told Us. "I’m just trying to just focus on my music and stuff right now. I’m happily single. Single life is good. It’s not bad at all."
