Avril Lavigne and Deryck Whibley were spotted out having dinner at Koi restaurant yesterday. They are another young couple that seems surprisingly stable by Hollywood standards. No rumors about marital problems is always a good thing.And is it wrong that every time I see Avril, I want to run out die my hair some crazy color?!? The pink in her hair is so cute! Of course, it goes with her punk rocker image...haha, I'm not so sure that look would work for me :)
