sunglasses tank top Gwen Stefani jeans heels headband karate no doubt

Channeling Betty Draper from Mad Men with a 1960's flip and bright pink lips, Gwen Stefani rocked the vintage housewife 'do while still remaining true to her rock 'n roll roots with baggie jeans and a black lace tank.

The hot mamma made the parking lot her runway as she dropped off her boys, Kingston and Zuma, at karate in Sherman Oaks before stopping in at Hugo's for a bite to eat on Sunday.

Gwen's hubby, Gavin Rossdale, has been busy touring with his band Bush -- his recently- reunited band plays in Montana on Tuesday.
