Katherine Heigl

Katherine Heigl almost debuted more than just her darker hair color.

The newly brunette Grey's Anatomy star caught her dress strap after it broke while she was accepting the Female Star of the Year award at the ShoWest convention in Las Vegas last week, according to E! News.

The show's emcee, Billy Bush, swooped in and held Heigl's strap in place as she finished her speech. Heigl later secured the strap with a safety pin.

In non-fashion emergency news, the actress said that her new dark 'do is for her role as a young female bounty hunter in the movie adaptation of Janet Evanovich's Stephanie Plum book series.

"She's a very specific kind of girl, and I didn't want to disappoint the fans because I know what it's like when your favorite book gets made into a movie and it's not what you had hoped," Heigl told E! prior to her strap snap. "I wanted to go out there and show the fans I'm committed to Stephanie."
