The 40-year-old mother of two - Kingston, 6, and Zuma, 3 - has revealed in an interview with Harper's Bazaar for their September 2012 issue how she maintains her athletic figure. She said, "there is no secret: You just have to eat healthy, work out, and torture yourself!"

She also tries to hit the gym whenever she has a free moment in between taking care of her two kids. Being the lead singer of No Doubt, Gwen also notes that jumping around on stage during their shows also counts as great cardio.

On her relationship with her rocker husband Gavin Rossdale - who is the frontman for the band Bush - Gwen reveals that her secret to making the 46-year-old like her more is makeup. "I already put my makeup on twice today: I put it on to take my kid to school, and then I went home, washed my face, and put it on again to have lunch with you," she says in the interview.

"I like to make my husband like me more," she says, "and he likes it when I'm wearing makeup."
