Gwen Stefani wears red lipstick because her husband likes it.

The No Doubt singer - who has had huge success in The Fashion world with her L.A.M.B. clothing label - revealed her trademark red lips are not a fashion statement but simply a favourite of Gavin Rossdale and also admitted she takes inspiration from "hot" girls in the street.

She said: "I don't have a favourite brand, I switch it up all the time. I change colours too, I was wearing Pink lipstick the last day but I wear red for my husband because he likes the red.

"I get inspiration from everywhere, it could be anything, it could be some hot girl walking along the street and I go 'I wanna be like her'."

Gwen revealed she has always been interested in fashion but doesn't put too much time into thinking about her style.

She explained to "My style is always evolving, it always has ever since I was a little girl. It's just something that's really organic and natural. I don't put a lot of thought into it in the sense of 'what am I going to do next?' it just kind of happens.

"I have loved playing dress up since a very young age. I'm a typical girl in that I love getting dressed up to go out but when I get there I take a look around and then want to go home. I'm all about getting ready."
