Hayden Panetierre went to the Golden Globes HBO after party last night wearing a blue dress that showed off just a little more than she intended. Everyone could see her nipple covers! It could have been worse - she could have unintentionally flashed the photographers.

Hayden stars in the upcoming romantic comedy "Naomi and Ely's No Kiss List" as a woman whose friendship with her best gay male friend is strained when he crosses the line by kissing her boyfriend.

Amy Andelson and Emily Meyer adapted the book by "Nick and Norah's Infinite Playlist" authors Rachel Cohn and David Levithan for Fox Atomic.

She also stars in "Scream 4." Neve Campbell, David Arquette, Courteney Cox Arquette, Emma Roberts, and Rory Culkin rounding out the cast.
