It was bound to happen sooner or later.
NBA player and newlywed Kris Humphries, 26, was among those with a front row view of the inadvertent peep show. Other stars at the event included Austin's husband, rapper and actor Ice-T, 53, and Kirstie Alley, 60.
Despite the boob flash, Austin remained upbeat post-show. "Today is 'Titty Tease-day' instead of Tuesday. Get it?" she tweeted. "At home I'm somewhat of a nudist. It feels good to be free."
