Rosario Dawson accidentally flashes her underwear as she climbs the Cannes stairs just days after Longoria exposes all

Is flashing your underwear now the in thing?  Eva Longoria revealed far more than she intended to at the Cannes Film Festival on Saturday.

And Rosario Dawson suffered similar fate as she attended the As I Lay Dying premiere in the French City on Monday night.

But thankfully she was wearing white underwear when her stunning white Elie Saab gown parted at the front split to reveal all on those infamous Cannes red carpeted stairs.
