He's such a hair chameleon!

Justin Bieber hit the Bryson Tiller concert at The Wiltern in Los Angeles last night, and the singer opted to go for a different look by pulling his peroxide locks into a high ponytail. Is it bad that we think he looks super sexy like this?

Where was Hailey Baldwin, though? Ever since The Biebs got back from the Caribbean he hasn't been spotted with his rumored model girlfriend, and we have a feeling they're dunzo! According to new reports, JB realized after his romantic vacay that he just simply doesn't have time to be a good boyfriend.

"Not only is it an issue of scheduling, but [Justin Bieber] just doesn’t want a girlfriend. He has too many things going on. He feels that now is no time to be tied down to one woman. It would be selfish of him because he knows he doesn’t have the proper amount of time to nurture a healthy relationship, so he is just having fun… He really is enjoying being single and loves spending time with pretty girls, even if some are just friends," a source dished to Hollywood Life.

Other celebs in attendance included French Montana, Diddy, Rihanna, and Kylie Jenner!

Speaking of the plastic surgery princess, when we asked her if her brother was dating Tyga's ex on her way out of the venue, she shouted an audible "No" as she hopped into her awaiting vehicle. Sounds like wishful thinking!
