Katherine Heigl nearly showed off more anatomy than she wanted to while accepting the award for Female Star of the Year at the ShoWest awards in Las Vegas last night. During her acceptance speech, a strap on her dress detached from the back. She gasped in surprise, grabbing it just in time to keep from flashing the audience. Host Billy Bush quickly stepped forward to hold the strap in place while she completed her speech. Heigl was chosen for her post-Grey’s Anatomy work in feature films such as 27 Dresses and The Ugly Truth. “Her ever-present charm and innate talent have made Heigl’s transition from TV screen to silver screen seemingly effortless,” said Robert Sunshine, co-managing director of ShoWest. “Her comedic timing and flair for acting are showcased in each of her roles and have captivated audiences around the globe.” Other ShoWest award recipients were Avatar‘s Sam Worthington as Male Star of the Year; The Hangover director Todd Phillips for Filmmaker of the Year; Zack Galifianakis as Comedy Star of the Year; Vanessa Hudgens for Female Star of Tomorrow; Alex Pettyfer for Male Star of Tomorrow; and Amanda Seyfried as Breakthrough Female Star. The Lifetime Achievement Award went to producer Jerry Bruckheimer. ~Alexandra Heilbron
