Former Busted star Matt Willis has blasted rocker Pete Doherty over claims the Babyshambles frontman finds rehab a doddle - as it's insulting to people who use it as their last chance to seek help. The pop star, who recently won the reality show I'm a celebrity...GET ME OUT OF HERE!, has checked in celeb rehab clinic The Priory twice- the last one taking place in April this year (06), for drink problems. And he can't understand why Doherty would demean the treatment, when it gives hope to so many people. He says, "What I don't understand is why Pete Doherty says that rehab is a doddle. Some people there are close to death and go there for help, so it's insulting."
