In the middle of doing interviews at a glitzy TV Academy event in honor of Glee, the actress, who plays Mercedes on the show, collapsed.
She reportedly was working all day shooting another episode and went straight to the event. Riley eventually tweeted, "Hey guys, I'm okay :) I got a little dizzy from all the photog flashes! You'd think I'd be used to it by now, still a red carpet amateur I guess. Gonna get checked out but I feel fine. Thank you for all the concern and well wishes."
The star, who also paid tribute to Whitney Houston in a recent episode, said, "I'd also like to thank the photographers for being so professional and not taking photos of me on the ground. I truly, truly appreciate it. Could have been super embarrassing."
Despite the health scare, Riley was able to participate in the show's panel presentation by the night's end.
