When Chris Brown played the Summer Classic Charity Basketball Game in NYC on Thursday night, he saw a very familiar face sitting courtside — his former girlfriend Rihanna. The Barbadian singer was on hand to cheer on a mix of celebrities and athletes (including her infamous ex) as they played a friendly game at Brooklyn's Barclays Center. While Rihanna and Chris didn't interact on the court, she did appear to be having a good time as she chatted with her group of girlfriends, including model Cara Delevingne. Unfortunately, the singer didn't show any of her trademark game-watching antics. She was probably resting up considering that she is currently in the middle of the Monster Tour with Eminem. The pair will end the limited tour this weekend when they play two final shows in Detroit. While she's in the middle of her own run of shows, she took a break to cause quite a bit of commotion earlier this week when she attended Drake's concert in the Big Apple, sparking up new rumors that the on-again, off-again couple are back together.
