Canadian singer Avril Lavigne has been chosen to represent her country at China's forthcoming 2010 World Expo. The pop punk princess is named as ambassador at the event.

Avril Lavigne's husband has warned Paris Hilton's ex-boyfriend to stay away from her. Rocker Deryck Whibley was reportedly furious after he discovered Avril had been out for dinner with oil heir Brandon Davis - who has also dated Lindsay Lohan - and texted his love rival saying: "Stay away from my wife."

The 'I'm With You' singer insists on being the sole blonde on stage when she performs live, and so orders all her dancers to dye their hair. She said: "Everyone was brown, except one of my favorite girls was blonde so we were like, 'You have to have brown hair.' It wouldn't look right. "I wanted my girls to look really punk rock with like black hair and that's pretty standard for everyone, like Madonna and Mariah Carey. If they're blonde you're not going to see another blonde on stage." Meanwhile, Avril - who recently celebrated her second wedding anniversary with Sum 41 rocker Deryck Whibley - insists she has no plans to start a family just yet. The 23-year-old singer said: "I don't want to have kids for like 10 years. I still have a lot to do. I don't even know if I could handle a dog right now. I'm so not ready. Someday I'll be a mom but not until I'm in my 30s."
