You might wanna turn away, Selena Gomez.
Justin Bieber did not spend the weekend only in the company of Floyd Mayweather, getting pampered alongside the boxer.
In Last Vegas for that athlete's championship fight, Bieber also spent time with Kylie Jenner and a model named Yovanna Ventura - and we've got the photographic evidence to prove it!
An insider tells E! News that Bieber hung out with Jenner Hard Rock Hotel, though it's unclear where this selfie was snapped.
Sure looks someplace dark and intimate, though, doesn't it?
Recent reports have indicated Justin has been spending a lot of time with both Kylie and her sister, Kendall, a relationship that has severely bothered Gomez.
According to one source, Bieber even cheated on Selena with Kylie this spring.
It's a delicate situation, one not made any easier by Bieber photographing himself with the reality star and also with Ventura, a young model out of Miami.
These two looks rather cozy together, wouldn't you say?
