Rihanna sat courtside at the Brooklyn Nets vs. Miami Heat playoff game in Miami on Thursday, but focus was placed on her left hand. The stunning singer showed off what appeared to be a diamond ring on her engagement finger, causing speculation that someone recently proposed to her.

Did rumored boyfriend Drake propose to Rihanna? A source close to the singer tells Hollywood Life that it is not an engagement ring. It is unclear if Rihanna and Drake are even together still, as they have not been spotted out together in recent weeks.

In February and March, the two continuously showed public displays of affection, even holding hands after partying together. But the two have not been hanging out together lately.

A source tells the site that they still remain in contact when they are not together, but Rihanna may want more attention than he is able to give right now. “He sends texts, he’s staying in constant communication.… She misses him entirely. That’s all and she wants him to drop everything to constantly be with her,” a source close to Drake said.

Meanwhile, Chris Brown is reportedly planning to marry Karrueche Tran after he is released from jail, even though they recently split up yet again. “He basically told her that when he gets out, things are going to be way different between them and that he’s going to return all the favors she’s given him with a surprise of a lifetime,” a source said.

Brown, 25, is in jail pending his trial in May for assault. Police say Brown and his bodyguard Christopher Hollosy attacked a man last year with their fists outside the W Hotel in downtown Washington last year.
