Unlike most women in Hollywood, Gwen Stefani doesn't claim that she can eat whatever she wants and somehow still stay slim. In fact, the mother of two admits that keeping her tummy toned is a daily struggle.
"I work out five days a week," Stefani tells the April issue of Elle U.K., according to the Daily Mail. "I can’t imagine not doing it."
While Stefani admits to being a big fan of pizza—and even treated herself to a slice after presenting her Spring 2011 L.A.M.B. clothing collection at New York Fashion Week last September—she is very careful about her diet.
"I'd like to have no rules and eat what I want, but I've learned over the years that I'm so disappointed when I can't wear the clothes I want to wear," she tells Elle U.K. "And if I let myself down, appear on stage when I'm not looking my best, it's not fun for me. I just beat myself up about it."
The singer, who is married to rocker Gavin Rossdale, is equally strict about her beauty routine and confesses she wouldn't dream of leaving the house without her face on.
"I wear makeup every single day," she says. "I like to wear makeup for Gavin and I don't feel energized till I've put it on. Then I'm ready to go."
