tank Gwen Stefani sports bra marilyn monroe no doubt red lips

Gwen Stefani was spotted running errands in Los Angeles yesterday, and while her face looked immaculate, based on what she's wearing we're thinking she was either headed to or from the gym. Gwen recently admitted that she's been taking it easy on her workouts, but it's pretty obvious that she still hits the treadmill every now and then...

Gwen also opened up about her relationship with hubby Gavin Rossdale in the new issue of Marie Claire, telling the mag, "My biggest accomplishment is my marriage so far. Because it’s hard, everyone knows it’s hard. [Marriage] is something that I always wanted to do successfully. It was a dream of mine. I like the official-ness and the family-ness of it all, having the same name and making decisions together.”

Can you believe Gwen and Gavin tied the knot TEN years ago this week? In Hollywood that's practically an eternity!
