"Glee" star Amber Riley caused concern when she collapsed on the red carpet Tuesday, but she's since assured everyone that she's just fine.

The 26-year-old actress was walking the carpet while attending a panel discussion in North Hollywood, Celebuzz reports, when she said she was overwhelmed by the flashes from the photographers' cameras.

"Hey guys, I'm okay," she posted to her Twitter account Wednesday. "I got a little dizzy from all the photog flashes! You'd think I's 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."

She added a thank you to the photographers for "being professional and not taking photos of me on the ground. I truly truly appreciate it. Could have been super embarrassing."

The collapse, however, sparked a healthy amount of gossip that it was something besides cameras flashing that caused Riley's scary experience.

Later on Wednesday, Riley addressed the gossip with a smile, admitting that some of the speculation had made her chuckle.

"Let me stop the rumor mill right now," she wrote. "I'm not pregnant! Yes I'm black but I don't have diabetes, I don't starve myself to fit clothes; I buy clothes to fit ME not vice versa, I DO NOT DIET; I eat right and exercise! I love myself waaaay more than I like my career. I would never ever put myself in harm's way to mirror any 'image.' Come on [people]. Get a life. I did get a great laugh this morning reading all the BS though lol."
