(CNN) -- Perhaps Sandra Bullock was just overwhelmed. The "Gravity" star had a busy Thursday thanks to her Oscar nod, and by the time she took the stage at that night's Critics' Choice Movie Awards, she let an F-bomb slip during her acceptance speech for best actress in an action movie. Bullock was trying to get out her "thank you's" when a technical glitch interrupted. "What the f***?" a surprised Bullock said before joking that she's an action star. The 49-year-old wasn't the only to go off-script that night: Bradley Cooper sneaked in the expletive during the best comedy acceptance speech, calling his co-stars "these f***ing actors."
