Are Chris Brown and Rihanna Hanging Out in Secret?

Rihanna made her way to Greystone Manor last night in a revealing, black body suit. After all, blondes have more fun! The 23-year-old singer sported her new blonde locks and topped off her ensemble with a black and gold Chanel hat. Rih-Rih reportedly partied it up at the same time as former-beau Chris Brown.

Of course the two did not arrive together and weren't photographed with each other, but their tweets definitely suggest something is up.

With Rihanna tweeting "What a crazy night?!!" and Chris tweeting "Can't stop lookin," it makes things seem like they were focused on each other.

To add fuel to the fire, one of Karrauche's (Chris current girlfriend) friends, Seiko, tweeted "Concealing what you're doing, or who you're doing it with due to lack of confidence or belief, is an indication of insincerity."

With all the sub-tweeting and partying at the same clubs, do you think Riri and CB are getting back to their old love? Share your thoughts!
