Former BUSTED singer Matt Willis has vowed never to work with friend and former bandmate James Bourne again, because the SON OF DORK star is crazy. Willis quashes rumours of a possible reunion, but insists Bourne remains a close friend. He says, "I don't think I could stand to do anything with James again. He's too much for me now. "Recently I've been hanging out with him and thinking, 'How did I put up with you for five-and-a-half years? How did I live with you for five years?' I don't know how I did it. "He's the craziest kid I've ever met in my entire life. But he's wicked and I love him to death. He's my best mate." Busted disbanded in 2004 following Charlie Simpson's decision to focus on rock group Fightstar instead. Willis adds, "I would have kept on doing Busted for a couple more years. I loved Busted and everything we did - so did James. "But towards the end it was not great, 'cos we had someone f**king moaning all the time. "Obviously Charlie had other plans and I'm happy for him he's doing really well. I bought Fightstar's album. It's amazing."
