The countdown is on for Beyoncé … in more ways than one!

As the mom-to-be counts down to baby, she's putting out a new video for her next single, "Countdown," which premieres Thursday (7:56 p.m. ET) on MTV and her website.

But you can watch a 30-second sneak peek of it above.

Dressed in a beatnik-black turtleneck, Beyoncé flirts and flutters her eyelashes at the camera as the upbeat love anthem begins. Later, the singer, whose hair is done up in a dark cropped do, dances around in front of a black-and-white background, before beginning the catchy count backwards from ten to one (which samples the Boyz II Men song "Uhh Ahh") that acts as the song's chorus.

When she gets to the last lines and sings, "I'm trying to make us three / From that two / He's still the one," Beyonce shows off her growing baby bump, which is significantly bigger than it was when she first debuted it in August at the Video Music Awards.

And just like that, Beyoncé and Jay-Z's unborn child becomes a music video veteran.
