Katherine Heigl's wardrobe malfuction at ShoWest

Katherine-Heigl-ShoWest.jpgWhen co-managing director of ShoWest, Robert Sunshine, said Katherine Heigl was being named Female Star of the Year in part for her "comedic timing," well, he had no idea how good her timing could really be.

While ( soon-to-be ex?) "Grey's Anatomy" star accepted her award onstage Thursday (March 18) night in Las Vegas, her dress straps broke. Yes, during her speech.

Luckily the night's emcee, Billy Bush, rushed to the rescue and held her straps in place while she made it through her speech.

Not missing a golden Twitter opportunity, Bush posted the incident on his page:

"Oh my. Hosting showest awards in LV. Heigl comes up to get award, dress strap breaks...I hold her top on while she accepts!"

Bush didn't have dress strap duty all night though. A safety pin secured her dress in the press room afterward.
