Glee star Amber Riley has laughed off reports suggesting pregnancy, an eating disorder or diabetes was to blame for her collapse at a red carpet event on Tuesday.

The actress, 26, was attending a Glee screening at the TV Academy of Arts and Sciences in North Hollywood when she fainted in the middle of a press interview.

She blamed the incident on the flashing of camera bulbs and assured fans she was "fine," and admits media speculation about her dizzy moment has left her baffled.

In a Twitter.com post on Wednesday, she writes, "Lol (laugh out loud). Let me stop the rumor mill right now. 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 ppl (people). Get a life. I did get a great laugh this morning reading all the BS (bulls**t) though."
