Time for Bieber to swoop in and ruin everything!

Selena Gomez has been quietly hooking up with pal Charlie Puth, Us Weekly reports. "It’s not serious, but she’s super into him,” a source dished to the mag, while another insider downplays the romance as just a "flirty friendship."

The pair previously recorded the duet "We Don’t Talk Anymore” for his debut album Nine Track Mind, and he will hit the road with his new lady on her Revival tour in May. They better hope they're still on good terms by then, or else that could be super awkward!

Puth has been quite vocal about his admiration for the "Come & Get" songstress, so there's no doubt he's stoked to have finally had a shot with her. “I just went up to her and started talking to her. I was very floored by how well she handled herself and how mature she was. It’s nice to get to know the actual person and finding out she’s an interesting person ... I’m happy that we’re friends," he previously told Us Weekly about the first time he met Gomez at the MTV Video Music Awards last August.

This news isn't going to go over well with The Biebs! “He’d love to be with her, but she won’t go for it," another insider revealed to the outlet. We all know the brunette bombshell has a terminal case of Bieber fever, so all the Canadian crooner has to do is make some empty promises to her and this new coupling is kaput!
