Nine months of togetherness and it looks like Paris Hilton is already ready to split from Benji Madden, the man she described as the love of her life.

The hotel heiress and Good Charlotte rocker have not been seen together for over a week, sparking speculation about their relationship pretty much kaput and done with. But, what could have gone wrong, as only recently they signed a six figure deal in Australia for the launch of a new social online networking system Bongo Virus New Year bash, to be hosted by Paris with Benji as the DJ.

Insider news from someone associated with the Australian company reveals Prince William, who is pretty keen on her after spending time with Paris during the filming of Hilton's My BFF show in London , has plans to meet up with her to ring in the New Year together.

While, no representative from the Royal Family could be reached, Bongo Virus confirms Prince William has been issued an invitation to the New Year's Eve bash, and while Benji and Paris may not come together, Paris will definitely be there.

A very quiet and very controlling Benji, one of the reasons his ex-fiancee Sophie Monk split from him, was very irked by all the extra attention Prince William paid Paris. And as for Paris 's perennial partying and love of the nightlife, ensured things were rough sailing for the two.

As well, Nicole Richie may have added more strain to the relationship, as though she may have denied it, she never really approved of her childhood friend dating her fiance's twin brother.

However, Hilton remains unfazed in top form, partying well into the wee hours, laughing, joking with galpals and going wild dancing on the couches.
