Beyonce Knowles may be taking some time off, but that's not to have a baby because, as the star reveals, she's still too "ambitious."

"My ambition is to continue to learn about the world and to eventually have a family," she told You magazine, adding that she's planning "no dates, no times – it will happen when I am ready."

But Beyonce, who is debuting a new perfume called "Heat", says her life is so hectic that she already feels like a woman who has a child. "Probably the biggest challenge in my life is time – making sure I have time to be a wife, to be a singer, to be a songwriter, to be an actor and still have time for my clothing line and now for my perfume. I am like any other woman who has a child, who has a husband, who has a job. I think it’s the hardest thing about being a woman because we have so many responsibilities."

She may not be ready to take on an additional one right now, but we can't imagine the 29-year-old will be waiting until she has an Oscar to start trying for a little Jay-Z junior!
