Entertainment Tonight reports that "Glee" star Amber Riley during a cast screening and Q&A Tuesday in L.A.

Amber later 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 event was held by the producers and cast of "Glee" for members of The Academy of Television Arts and Sciences. Other cast members in attendance included Lea Michele, Matthew Morrison, Cory Monteith, Darren Criss, Chris Colfer and Jane Lynch.
