{blackbabes} Beyoncé: Babies and Retirement at 30?

Avatar (Blu-ray) (With DVD) (Special Edition) (Widescreen)

Beyoncé once had big plans for the year she turned the big 3-0.

"I always said I would have a baby at 30," the singer, now 29, told her host Monday on Piers Morgan Tonight. "But I also said I was gonna retire at 30."

With only months to go until her Sept. 4 birthday, the artist says "only God knows" when she will become a mother with husband Jay-Z – and she's not ready to retire.

For now, she's focusing on her music. Her fourth studio album, aptly titled 4, just dropped Tuesday.

And she's not fearing the new milestone. "I can't wait," she says, "because 29 is very strange."

"You're still in your 20s," she explains. "But you feel like you're supposed to be 30, and I feel like a woman."

She adds: "I feel like 30 is the ideal age because you're mature enough to know who you are and to have your boundaries and your standards and not be afraid of [being] too polite. But you're young enough to be a young woman, and I'm so looking forward to it."
