Beyonce’s “Countdown” features a very special guest star — her baby bump.

The wife of Jay-Z and mom-to-be shows off her growing belly in a sneak peak of the “Countdown” music video released this week. Clad in all black, Beyonce faces the camera and shakes against a black and white background. When she sings,  ”I’m trying to make us three,” she turns to give the camera a profile view of her bump.

The full video will premiere Thursday, according to MTV. Beyonce revealed her pregnancy at the MTV Video Music Awards in August.
