Chris Brown’s girlfriend Karrueche Tran will probably not be pleased when she reads about this. There’s been a lot of talk lately about Rihanna and Chris Brown reuniting and hooking up again years after their big breakup. Adding fuel to the fire is a new report that the two spent hours together in her dressing room.

They were apparently having so much fun together that she didn’t care about holding up her rehearsals for the Grammys. It’s unclear whether they were alone the entire time when inside; he left the room with a male friend. Karrueche Tran was nowhere to be found.

Whatever they’re doing with each other, Rihanna’s management team probably wishes it would end. She’ll certainly get a lot more slack for remaining on friendly terms with someone who so viciously beat her up, coincidentally right before the Grammys, three years ago.
