This surely has to be the weirdest celeb mix on record.

Last night saw London club Whisky Mist play host to bizarre mix of royals and Hollywood blondes...

As Christina Aguilera and Paris Hilton rubbed shoulders with Prince William and Princess Beatrice.

Christina Aguilera, Prince William, Paris Hilton and Princess BeatriceAll four stars, bred from very different backgrounds, chose to spend their evenings at the hot London nightspot.

The blend of babes and blue blood were snapped leaving the venue separately...

But who knows whether they mingled together within?

Or what they found to talk about, if they did?

If the Showbiz Shed were flies on the wall we reckon the conversation would go a bit like this...

Prince William breaks the ice with a few anecdotes about  the spiffing time he and Kate had at Highgrove recently, as Paris Hilton chimes in that it sounds, like, totally super-hot.

Paris then tries to recruit Princess Beatrice as her new British BFF, promising her an "awesome" time, but Bea replies:

"Sorry old girl, sounds terrific fun, but afraid I'm rather caught up attending university this term. Next time, what, what?"

Christina Aguilera then rounds things up by telling everyone how relieved she is that her post-baby cleavage still soooo totally rocks.

"Here, here," Wills finishes off.

Yup, we reckon that's how it went down. If only we could've been there. Sigh.
