Princess Paris Hilton

Paris Hilton and boyfriend Benji Madden

Paris Hilton wants to date Prince William - when he gets rid of his "mousy" girlfriend.

The hotel heiress met the future king - who has been dating Kate Middleton for around five years - on a recent night out and admits that despite being in a relationship with Good Charlotte rocker Benji Madden, she would act on her crush if William didn't have a girlfriend.

Paris told New! magazine: "I'd be more than happy to date William - so long as he ditches the mousy girlfriend. I couldn't believe it when I met him. He was awesome and really hot."

The 27-year-old blonde - who met William, 26, at exclusive London nightspot Whisky Mist - recently rubbished claims the royal had flirted with her.

She said: "People made out that he was flirting but he's an absolute gentleman and wouldn't do that. He just came over to introduce himself.

"He knew about my show and why I was in London so we talked about that for a while. He's just a really sweet down-to-earth guy. So is Harry. "
