VIDEO : Only Gwen Stefani Could Make Going to the Nail Salon Look This Cool

Gwen Stefani was the picture of rocker cool while leaving a nail salon with her eldest son, Kingston Rossdale, in LA on Monday. The singer sported a pair of denim overalls and cat-eye sunglasses while also showing off colorblock black and purple hair and her signature red lipstick. Gwen debuted the edgy new hairstyle on Instagram over the weekend before hitting the stage with No Doubt at Riot Fest in Chicago; she posted a series of snaps from their performance and revealed that she even took some classic Chicago deep dish pizza home with her.
