The singer says she and husband Jordan Bratman plan to start a family – just not quite yet

Christina Aguilera and her music exec husband Jordan Bratman plan to have kids – just not quite yet, according to the singer.

“In five years time I’d probably like to start thinking about a child,” the 25-year-old star said on Britain’s GMTV morning show Friday, “and probably writing about that experience in my life on my next record.”

In fact, she says her personal life is usually reflected in her music, including her current single, “Ain’t No Other Man,” which she performed Thursday at London’s Koko club.

“I definitely write according to specific things that are going on in my life and just having been married there is definitely one man in my life and there ain’t no other man.”

As for her marriage, Aguilera, who is known for her defiant self-confidence, says in a new interview that she wished she had a father figure to walk her down the aisle last November.

She tells Billboard magazine in its new issue that, when planning her Napa Valley wedding to Bratman, she thought, “I’m a performer. I can totally walk myself down the aisle.”

But as she walked toward her groom to the sound of “Ava Maria,” “I just realized it would be really nice to have that male protector in your life, to have felt that your entire life, and to have that one person give you away to the next man that’s going to take care of you.”

Aguilera was 6 when her father, Fausto, an Ecuador-born U.S. Army sergeant, and mother, Shelly, separated. Aguilera and her sister, Rachel, moved with their mom from Staten Island, N.Y., to the Pittsburgh suburb of Wexford, Pa., and Aguilera has had virtually no contact with her father since.

Aguilera, who is about to release her new album, the two-CD Back to Basics, says of her childhood, “I never really had this father figure, which never bothered me. I had my mom, I had people that did love me and care for me.”

Back to Basics

pays homage to vintage jazz, soul and blues styles, which Aguilera says inspire her. “Not to say that music today doesn’t have heart, but it’s really few and far between because technology has advanced itself so much that anybody can be a singer,” she says. “Back in the day, you had to know how to sing.”

However, there is one contemporary artist she admires: Madonna. “I saw her last tour,” she says. “I’m looking at this woman, she’s got two kids at home, (and) she’s still able to do it. She’s got the stamina to be up on that stage, she looks amazing and it’s just really inspiring. And so I look at that and go, ‘Wow, I’m 25, what am I complaining about? I better get off my butt.’ ”
