Weve been speculating whether Chris Brown and Rihanna were getting back together . . . but apparently theyre doing MORE THAN JUST THAT . . . theyre getting MARRIED!!!

Two separate friends of Rihanna told Star magazine that she and Chris were GETTING MARRED. The mag claims, [Chris] proposed in November, but [Rihanna] said she wasnt ready . . . But she finally accepted the proposal in late February. Shes not wearing a ring until they can announce it at an engagement party, but Rihannas already told her friends and family that shes engaged.
