Beyonce Features Baby Bump in "Countdown" Sneak Peek

Jeff Kravitz/FilmMagicBeyonce's baby bump makes a quick cameo in a 30-second teaser of the mommy-to-be's music video for "Countdown," a song from her latest album, 4.  The sneak peek starts with a close-up of Bey rocking a black wig updo and black turtleneck, and shows her in a couple different numbers, including a loose black and white gown.  When Beyonce sings, "I'm tryna make us three...." she gives the camera a profile view of her growing tummy.  The clip closes with a shot of four, side-by-side Beyonce clones standing in front of a yellow backdrop, and wearing primary colored leotards with black-and-white hats.

MTV reports the full video is set to premiere Thursday.
