Actress Tina Fey suffered an embarrassing wardrobe malfunction onstage at the Primetime Emmy Awards on Sunday (22Sep13) after accidentally flashing her nipple as she accepted a prize.

The 30 Rock creator and star was picking up the honour for Outstanding Writing for a Comedy Series with her pal Tracey Wigfield at Los Angeles' Nokia Theatre when the plunging neckline of her blue Narciso Rodriguez dress shifted and revealed she was not wearing a bra.

Fey appeared not to notice her brief moment of overexposure and the blink-and-you'll-miss-it incident aired unedited during America's live broadcast on Sunday.
