Rihanna Tickets

Rihanna and Chris Brown reportedly got up on stage to sing together last night while partying at the Greystone Manor in West Hollywood.

The former couple appear to be regulars of the new celeb haunt and were first spotted attending on the same night last month. While they reportedly did not speak to each other that time, an eyewitness says they made contact last night and even reunited on the stage.

According to Global Grind, an eyewitness who was in the club at the same time, wrote on Twitter: "Greystone Manor was crazy tonight.. Rihanna & Chris Brown together.. Singing reunited and it feels so good!!"

Breezy tweeted while he was in the club, writing: "Can't stop lookin," while RiRi told her followers she had a "crazy night."

It is not known if Breezy's girlfriend Karrueche Tran was in the building at the same time, but she did post a photo on Twitter with some friends in a club.

Just last week, RiRi laughed off the rumours that she and Chris were getting back together, while his rep has previously denied that he is cheating on Karrueche.

Do you believe RiRi and Chris will get back together?
