A Baby At 30 For Beyoncé?

For years, pop superstar Beyoncé Knowles thought that at 30, she'd be ready to retire from her successful music career and start having children.

But with her fourth studio album, 4, now in stores, and the big 3-0 approaching, B isn't showing any signs of slowing down. So what does this mean for her baby plans?

"I always said I would have a baby at 30," Knowles tells CNN's Piers Morgan. "But I also said I was going to retire at 30."

With no official plans of motherhood, Beyoncé says that "only God knows," when she and hubby Jay-Z will become parents.

In the meantime, she's looking forward to saying goodbye to 29.

"I can't wait," says Knowles of her September 4 birthday, "because 29 is very strange.

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

"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."
