blonde sunglasses all black medical building necklace

We love Gwen Stefani's chic punk style, and the sexy singer is still rockin' the same trademark red lips and bleached blonde hair that she made famous in her No Doubt days.

The fashion designer and mom of two arrived at a medical building for a doctor's appointment on Friday afternoon in Beverly Hills, wearing an all black ensemble, and some funky shades.

Gwen has been hard at work on her sixth No Doubt album, which is expected to drop on September 25, and she'll be performing on stage with the band this summer! Stefani recently Tweeted: "You may have heard the rumors... and yes, we will be performing on the Teen Choice Awards in July!!!"
