UPDATE: Riley just tweeted again. "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. Get a life. I did get a great laugh this morning reading all the BS though lol "

It was supposed to be a night of celebration for the cast of "Glee" last night -- but it took a scary turn when star Amber Riley collapsed on the red carpet!

Riley, who plays Mercedes on the show, was doing interviews at the TV Academy in Los Angeles on Tuesday when she suddenly fainted before a panel inside.

After the event, which Amber still participated in, she took to her Twitter to let her fans know how she was feeling.

"Hey guys, I'm okay :) 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," she said.

"Gonna get checked out but I feel fine. Thank you for all the concern and well wishes," she added.

She also took a moment to thank everyone on the carpet at the event, adding "I'd also like to thank the photographers for being do professional and not taking photos of me on the ground. I truly truly appreciate it. Could have been super embarrassing."
