Sir Elton John is planning an exclusive dinner party for Prince William and Kate Middleton.

The 'Rocket Man' singer - who was a close friend of William's mother, the late Princess Diana - and his partner David Furnish have planned the party, to which David and Victoria Beckham will also be invited to thank the young couple for their invitation to their April 29 nuptials.

A source told the interviewer: "Elton loves entertaining and hosting people at his home. He is touring America at the moment but he flies between there and the UK and comes to his Old Windsor home whenever a short break in his schedule allows.

"He has wanted to invite Kate and William to dinner for a while now to thank them for his wedding invitation. He always puts on the most incredible feasts fit for royalty anyway so they should feel right at home.

"The Beckhams will be invited but it depends on whether his club will let him travel."

Meanwhile, it has been reported that William will have his bachelor party - which is set to include a day of boating and water sports on the English Channel(26,03,11).

A royal aide told US Weekly: "It's all top, top secret but the dates have been marked off in the diary and security knows every detail.

"There will be plenty of booze and some legendary activities."
