Christina has been flaunting around recently with no bra on. She is currently in London promoting her album Back To Basics. We are happy to see she finally returned to the basics of wearing a bra and underwear. However, she made sure we all noticed by making the dress see-through. She's lucky her husband Jordan understands the business. Check out what Christina had to say on kids, marriage and Madonna:

"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."

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.' "
