Benji Madden is no longer Paris Hilton’s “love of my life.” The two split after nine months together and most media sources claim that Paris’ alleged relationship with Great Britain’s Prince Williams is behind the separation.

Paris and the Good Charlotte rocker haven’t been seen together for about a week now and they have been hitting up Hollywood hotspots separately fueling the speculation that their relation is as kaput as it gets. Madden was reportedly very angry when Prince William said he would be attending the New Year's Eve party Paris and he planned to host in Sydney, Australia.

Hilton and Madden reportedly signed a six-figure agreement to perform at the New Year's Eve party in Sydney. The party will launch Bongo Virus, a new social online networking system.

Reps of the two did not comment about the state of their clients' relationship.

Prince William, the second in line to the United Kingdom’s throne, allegedly spent quite a lot of time with the princess of the Hilton hotel kingdom while she has been filming her "Paris Hilton’s My New BFF" show in London. The Prince did not confirm his presence at the New Year’s Eve party in Sydney for security reasons, a source close to the royalty said.

Bongo Virus confirmed that Prince William had been invited.

"We aren't that worried if Benji and Paris don't want to come together," said a source familiar with the issue according to FoxNews.com. "But we know Paris will definitely be there, and we can't wait."

Paris, who currently appears on the big screen in "Repo! The Genetic Opera," has been photographed getting cosy with her ex Stavros Niarchos in Miami, according to another account.

However, Paris has made it clear as day light that she would love to date the Royal, but only if he gets rid of his girlfriend Kate Middleton. Prince Williams has been dating her for the past five years.

“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,” she said about the Prince.

“He's just a really sweet down-to-earth guy,” she added.
