Gwen Stefani has one of the best bodies in show business. And, now I know why - she works out.
She told British ELLE magazine: "I work out five days a week, I can't imagine not doing it,"
"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.
"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."
I hear you, Gwen. Now, if only I could replicate your willpower and discipline.
