Well, hello there, Kourtney Kardashian!

In a new NSFW Instagram post on Wednesday, the reality star gave fans a dead-on look at her backside captioned very simply, with a moon emoji.

Talk about "don't want none!" Kourtney looks absolutely amazing in the stunning shot, which comes just days after the 36-year-old was rumored to be getting romantic with Justin Bieber. A source close to Kourtney shut down the rumors to ET, saying that Kourtney "wouldn't go there," and she and the 21-year-old singer are "just close friends."

The rumor mill went into overdrive last Friday, after Kourtney attended Justin's surprise show at The Nice Guy in West Hollywood, California. A source told ET that the two "were nearly inseparable" throughout the night.

Despite the talk, Kourtney and her ex, Scott Disick, appear to be seeing if they can be back in each other's lives. Earlier in December, a source told ET that although the Keeping Up With the Kardashians star is not quite ready to take back the 32-year-old father of her children after his stint in rehab, they are "trying to make things work."

Kourtney has always held her family very closed, as evidenced by a throwback pic of her brother Rob that she posted on Tuesday, writing, "Bobby."
