Gwen Stefani reveals baby weight-loss battle

Gwen StefaniGwen Stefani (No Doubt) is urging new mothers to eat healthily as they battle to lose their post-baby weight, after she successfully slimmed down following the birth of her son, Kingston.

The singer avoided drastic crash diets taken by many celebrity mothers and lost weight gradually after Kingston's birth in May.

Speaking to "American Idol" host Ryan Seacrest on his Los Angeles radio show, Stefani said, "Let's just talk about how hard it's been.

"That's been really hard. But it's almost gone.

She says, "I jog regularly and I've just been eating healthy. I cheat every day at least once."

Stefani's new solo album, The Sweet Escape, will be released Dec. 5, and her latest single, "Wind It Up," which features a sample from "The Lonely Goatherd" from "The Sound of Music" is out now.
