Rihanna at Same Party as Chris Brown

Rihanna was at the same superbowl party as Chris Brown, a club in West Hollywood.  But the odd thing was, this was the same club that they were spotted at last month together at the same time.  Is there something going on that they have these secrets meetings?  They deny being back together and a rep has said that they just like messing with the press.  Chris states that he does in fact have a girlfriend.  It is not known if the two intereacted with each other while at the club.
