Earlier today, it was reported that Rihanna and Chris Brown were spotted last night together at Griffin, a club in New York's Meatpacking District, and that they may have been kissing in public. Chris Brown was also seen leaving the same hotel that Rihanna was staying in this morning.

And tonight, two credible industry sources just tweeted that Rihanna and Chris Brown were seen together entering the V.I.P. section at Jay-Z's concert at the Barclays Center in Brooklyn. Is this relationship back on? See the tweets below.
