Justin Bieber is keeping the rumor mill busy with a sneaky Instagram post that suggests he is Keeping Up with one of the Kardashians.
Standing with his back to the camera, an unknown brunette - possibly Kourtney Kardashian - is seen with her face obscured in a very comprising position.
He captioned the picture "Lord knows," in what could be seen as a dig at Scott Disick - Kourtney's long time boyfriend - who is known as Lord Disick.
The two were seen together on Friday night, and have also been rumored to be "casually hooking up."
