Rihanna and Chris Brown -- More Evidence They're Back Together

Rihanna and Chris Brown More Evidence ... They're Back Together

Rihanna and Chris Brown partied at the same club last night, fueling growing rumors they're back together.

The two singers left Greystone Manor -- a West Hollywood club -- separately, but they were both definitely there at the same time.

Several people who were at the club last night tweeted that as far as they could see Rihanna and Chris had no contact with each other.

The protective order -- requiring that they have no contact with each other after Brown beat Rihanna -- was lifted a year ago.
