Hollywood royalty Brad Pitt and Angelina Jolie are set to party alongside the real thing.
The couple are apparently hard at work planning a star-studded Olympic Games themed soiree to be held at London's Victoria & Albert Museum on July 25.
Topping their guest wish-list are the Duke and Duchess of Cambridge, as is Prince Harry.
With all three royals taking on the role of ambassadors of the 2012 games – it's likely they could accept the invitation.
And the prospect of William and Kate enjoying a double date with Brad and Angelina is sure to thrill fans of both couples.
"It's going to be an Olympics-themed party, with huge buckets of home-made cocktails on offer," a source revealed to the Daily Mirror.
"The who's who of British and American celebrity will be in attendance, and invitees have been ordered not to take any photos from their phones.
"Angelina is such a fan of the duchess that she reportedly wants to make a movie about her."
Other stars lined up for the party of the summer include David and Victoria Beckham, Sharon Stone, Michael Douglas and Catherine Zeta-Jones.
Guests will then be invited to continue the fun at an after party in Brad and Angelina's rented £20 million townhouse.
It wouldn't be the first time William and Kate have rubbed shoulders with A-listers.
Shortly after their wedding in 2011, they were the focus of attention in Tinseltown at a glittering BAFTA dinner.
On that occasion, the world's most famous faces clamoured for some time with the royals.
Nicole Kidman was just one of the stars who was impressed saying: "I think they are lovely, they just make you smile."
