Could it be just the stress? At an Academy screening of 'Glee,' Amber Riley passed out on the red carpet while posing for the cameras.

Amber tweeted saying that she just got dizzy from all the camera flashes, saying that she's still a "red carpet amateur."

Other sources have alternative explanations: pregnancy or hardcore dieting. Amber, of course, shot both of these rumors straight to the ground. But you have to admit, the star recently did lose two dress sizes after changing her eating habits.

We love you, Amber, but be sure to snack on something every now and then! Gotta keep up the strength to sing, girl!

What do you think--could Amber really be pregnant? Would love to hear your thoughts below!
