Uh oh... Selena ain't gonna be happy. The Biebs and Kylie Jenner hang out

Right, so just the other day Selena Gomez unfollowed the Jenner sisters on social networks

Insiders say it was because Kylie had been flirting with Justin Bieber.

Clearly Kylie and The Biebs don't give an ish, because the pair happily hung out together at the Floyd Mayweather boxing match over the weekend.

Kylie posted a pic of herself from the fight with the caption: “Good times at the @hardrockhotelLV getting ready to see @FloydMayweather tonight". Justin later tweeted the photo above of him with Kylie.

Ooooh, Selena's going to be hating on you two!
