According to Zap2It, they sat in the VIP section of the Barclays Center to watch the show.
For anyone keeping score, Chris' girlfriend, Karrueche Tran, wasn't anywhere to be found. In addition to last night's concert, Rihanna and Chris were spotted at 1Oak, another NYC club. Insiders told The New York Post they reunited at the club at 3 a.m.
Wonder what Karrueche thinks about all of this? Earlier in the week she Tweeted, "there's a difference between a man and a boy, and i prefer men."
Rihanna's been posting some cryptic messages here and there as well. The Barbados-born star Tweeted last night: "Tough times don't last…. But tough people do!!!"
