BeyonceHarpersBazaar230.jpgBeyonce is opening up to the latest issue of Harper's Bazaar about her newly famous baby bump, and her 10-years-in-the-making relationship with hubby Jay-Z.

The 30-year-old singer says she and Jay needed time to create a foundation for themselves before they could bring a baby into the world. She says:

    "We focused three years on our marriage and found that it brought us an even stronger bond and connection. ... If you are with the right person, it brings out the best version of you."

We can't believe the couple has been together 10 years already (they married in 2008)! Beyonce also explains why it was important to her on a personal level to wait for baby. "It was important to me that I gave myself time to focus on becoming the woman I want to be, building my empire, my relationship, and my self-worth, before I became a mother," she says.

And when she did get pregnant, why the big fuss over the baby bump reveal? "I put a lot of thought into how I wanted to unveil it," she says. "It was important to me that I was able to do it myself." Beyonce admits that she considered 70 gowns before deciding on the orange frock she chose for the MTV Video Music Awards in August.

The singer revealed Monday that she is due in February.
