It’s not every day you might run into your ex at the Grammy awards. It’s also not every day that they’re a hot commodity on the red carpet, but that’s pretty much what happened to Justin Bieber over the weekend.

When Justin showed up at Rihanna’s GRAMMY after party in West Hollywood, it was discovered that Selena was also there with her new beaux The Weeknd.

According to sources at Entertainment Tonight, Justin was seen leaving shortly after — apparently Selena was getting really handsy with The Weeknd.

Earlier that day, Justin was on Instagram giving major sarcastic shade to Selena’s new man, saying that “Starboy” (The Weeknd’s song) was his favorite. Oh man — even though he might not be over, perhaps it’s best to try and forgive??
