The Dreamgirls star sang before the game kicked off then returned to her dressing room and asked pre-game show producer Rickey Minor if her performance was alright.

"This was such an important performance, because it's the first time everyone has seen Jennifer. But she's in such a great place, with such great spirits and time can heal her wounds."
