Sasha Fierce is gonna be a mama!

Beyonce made a huge announcement outside L.A.'s Nokia Theater at Sunday's MTV Video Music Awards: She's pregnant!

The Grammy-winning superstar, 29, covered up her bod in a gorgeous, loose-fitting red gown by Lanvin -- and announced her huge news to photographers. (The singer's rep subsequently confirmed the pregnancy to Us Weekly.)

It will be the first child for the singer and Jay-Z, her husband of three years.

Indeed, the couple has had babies on the brain for a while. "I always said I would have a baby at 30," Beyonce teased on a June 27 appearance on CNN's Piers Morgan Tonight. The "Best Thing I Never Had" singer turns 30 September 4.

She and rapper-mogul Jay-Z (real name: Shawn Carter), 41, tied the knot in NYC in April 2008.

""He is amazing," she gushed of her guy, adding that he was a "good man."
