Gwen Stefani blonde sunglasses smile son zuma singer no doubt

She may be wearing a half dozen layers, but she still looks quite stylish! Of course, we'd recognize those crimson lips anywhere!

After dropping her boys off at school on Tuesday, Gwen Stefani made an errand run in Los Angeles, flashing us a quick smile before hopping in her car. And speaking of running, Gwen may burn a lot of calories chasing after her two sons, but she recently revealed that she took a major break from working out.

"This last year I kind of stopped working out," she told Marie Claire. "I think my body just needed a break. And so I did that, and focused more on feeling good as opposed to beating myself up."

But after getting a peek at her abs the other night, we find it hard to believe that she's completely given up the gym...
