The basketball match was the most open public outing that the pair have united for since it was rumoured that their relationship was back on earlier this year.
Rihanna wrote a message on Twitter after the game, saying: "Santa baby! Hurry down the chimney tonight! Is it too late to be nice?"
The 23-year-old also shared a picture on Christmas Day of Brown posing shirtless while she sat on the front of a car.
Over the Christmas period Rihanna was troubled by an intruder to her Barbadian property.
