Beyoncé bares her baby bump in the colorful new video for "Countdown," the latest single from her platinum-selling 4 album available in stores and online now. Channeling legendary British actress Audrey Hepburn, the pregnant singer transforms into a ticking clock in the Adria Petty-directed visual. A video for the album's next single—the André 3000-assisted "Party"—is expected to arrive very soon.
