Since Beyonce coyly announced at the MTV Video Music Awards that she and Jay-Z were expecting their first child , the pop diva hasn't been shy about showing off her baby bump.

That bump gets major billing in the superstar's characteristically kinetic new video "Countdown," which was directed by Adria Petty. After an opening sequence that's a hat-tip to Audrey Hepburn, Bey turns in profile and shows off just how far along she is.

"I'm very excited!" Beyonce told E! News last month while promoting her hew fragrance, Pulse. "I'm probably the happiest I've ever been."
