Beyonce: I Would Not Be the Woman I Am Without Jay Z

Beyonce seems to do it all lately. She brought the house down at this year's Super Bowl, she announced a new world tour and recently released new songs with her former girl group, Destiny's Child. And she does it all while being a mom to her 1-year-old daughter.

In a new interview with Oprah Winfrey for "Oprah's Next Chapter," the 31-year-old singer revealed she wouldn't be able to do it all without her husband, rapper Jay-Z.

"I would not be the woman I am if I did not go home to that man," she said.

Bey said the rapper has helped her "on so many levels."

"You know we were friends first for a year and a half before we went on any date on the phone for a year and a half," she said. "And that foundation is so important in a relationship. And just to have someone that you just like is so important and someone that is honest."

Beyonce give birth to her first child, daughter Blue Ivy, in January 2012. She told Winfrey that Blue Ivy's favorite nursery rhyme is "Row, Row, Row Your Boat." But the "Love On Top" singer said her daughter has not taken away her passion for performing.

"I feel like I did a show three months after I gave birth which was really crazy. I had clearly never given birth and didn't know that I would gain 60 pounds," she said, before clarifying that she gained a total of 57 pounds. "But I really wanted to know. I feel so fortunate to do my job. I love my job. I love singing. I love the way it feels."

Beyonce's interview with Winfrey will air Saturday, February 16, at 8/7c on OWN, just before her HBO documentary "Life Is but a Dream" airs at 9 p.m. ET

Bey promises to give fans an unprecedented look at the woman behind the mystique in the documentary.

"I feel like it's time. It's time for people to really get to know me and to see a different side," Beyonce said at a press conference earlier this month. The singer is anxious about how audiences will respond to her "Life Is but a Dream" release, explaining, "I'm really curious and scared, and every night I'm like, 'Now it's too late. It's coming out,' but I'm happy with it."

As executive producer of the autobiographical film, Beyonce said, "It was really interesting directing and editing myself and seeing all the mistakes that I've made and, you know, still putting it in the film, and seeing life as if it wasn't me."
