After performing at the 2011 VMAs, Beyoncé Knowles unbuttoned her sparkly jacket and rubbed her belly -- announcing her pregnancy to the world. The camera then cut to Jay-Z and Kanye West in the audience and their over-the-top jubilant reaction.

Married to Jay for three years, the star has said time and time again that she planned on having a baby by the time she was 30; well, B turns 30 early next month.

The power couple tied the knot back in 2008 in a private ceremony at Jay-Z's New York apartment, and since then, there have been years of pregnancy rumors that they've shot down.

In June, the singer told CNN interviewer Piers Morgan that she wanted to get pregnant.

"I feel like a woman. I feel like I'm very aware of who I am. I feel great and I feel like 30 is the ideal age [to start a family], because you're mature enough to know who you are and to have your boundaries and your standards, and not be afraid, too polite -- but you're young enough to be a young woman," she said. "I'm so looking forward to it."

The singer added, "I always said I'd have a baby at 30. But I also said I'm going to retire at 30. ... Only God knows."

In that same interview, Beyoncé talked about her husband.

"Jay and I have kind of made a decision that we want to be known for our music and not our relationships or scandals. But he is amazing," she said. "I definitely had a very natural friendship and connection with him. We've been together for a very long time and I'm very happy. Love is the foundation of everything, everything I do. My music is inspired by love -- from my family, my husband, my sister."

No word on when the baby is due.
