Trends come and go, but Gwen Stefani's red lipstick is forever. Whether hitting the red carpet or dropping off her kids at school, the singer can almost always be counted on to show up with her trademark red lips. "I remember sitting in my ghetto, beat-up Honda Prelude and putting on that lipstick in the rearview mirror and being like, 'Uh-huh, I like that. That's [it] right there.' I never stopped after that." We love that Gwen stands by what makes her feel confident no matter the circumstances!
