Paris Hilton claims she is "living proof" blondes aren't stupid. The 27-year-old heiress - who once told Los Angeles police "I'm not, like, that smart" - insists her bimbo character in "The Simple Life" was all an act.

She said: "I'm very intelligent. I'm capable of doing everything put to me. I've launched a perfume and want my own hotel chain. I'm living proof blondes are not stupid."

Paris Hilton still wants to marry ex-boyfriend Benji Madden. The hotel heiress - who split from the Good Charlotte rocker earlier this month - is believed to be taking a break from the musician to test how strong her feelings for him really are.

A source said: "Paris wants to know if she absolutely can't stand to be apart from him. That's her test to make sure this is the guy for her. She has felt something she has never felt before with anyone with Benji, but needs to be 100 percent certain she is ready to be Mrs. Madden."

Paris Hilton has been desperately trying to win ex-lover Benji Madden back. The heiress chased her former boyfriend across Los Angeles on Saturday night in an attempt to reconcile with him following their split last week.

Paris had reportedly been bombarding the Good Charlotte rocker with text messages, but he refused to reply. When Paris heard Benji was at the Villa nightclub on Saturday she decided to confront him and took pop star Avril Lavigne along for support.

Paris Hilton and Benji Madden split because Benji was jealous of her relationship with Britain's Prince William, it has been claimed.

The Good Charlotte rocker was said to be furious when William, who is second in line to the throne, told Paris he would be attending the New Year's Eve party she and Benji were scheduled to host in Sydney, Australia.
