Dream team: Pop princess Kylie Minogue teams up with screen siren Sharon Stone to duet and dirty dance at an Aids benefit in Cannes. Stone cajoled the star-studded audience into pledging £200,000 to hear Kylie sing two of her greatest hits

The pair sang a duet that may well go down as the most expensive in history.

Kylie agreed to sing two songs - with Stone providing the backing - after an audience in Cannes agreed to donate £200,000 a tune to an Aids charity.

The annual American Foundation for Aids Research party has established itself as one of the social highlights of the Cannes film festival and this year's event, held at Le Moulin de Mougins, did not disappoint.

Minogue, firmly back on the scene after her much publicised battle with cancer, agreed to sing Can't Get You Out Of My Head and The Locomotion - after £ 400,000 was raised. Stone, who hosted last night's event, could not resist the opportunity to sing along.

Guest included Dita Von Teese

The guests, who had paid £2,500 each for their tickets, could not have been more delighted. They are reported to have whooped and hollered at the climax of each song.

This year's charity party attracted some of the biggest names in Hollywood, among them George Clooney, Matt Damon, Goldie Hawn and Kurt Russell, as well as supermodels Claudia Schiffer, Elle Macpherson and Naomi Campbell.

Campbell, who celebrated her 37th birthday two days ago, said: "I was roped into this by Sharon. I'll do anything for her."

Michelle Rodriguez, the Lost actress who has been linked to Minogue's ex Olivier Martinez, was also at the event but said of the Frenchman: "He's just a good friend."

Others performing included Julian Lennon and the burlesque artiste Dita Von Teese. She gave what one report described as a "trademark" dance, performing around a giant 9ft lipstick.

Kylie, 38, has been a busy lady of late, and it seems is plotting world domination.

As the singer left her London home with her ever-present stylist William Baker, he held an envelope on which appeared to be scribbled evidence of her non-stop agenda.

Kylie Minogue appearing at Cannes

It starts with the word "mugs", suggesting she needs to do some shopping for the kitchen.

Next comes the phrase "tour next year".

Her Showgirls world tour only ended a few months ago. Fans will be thrilled to learn she plans another so soon.

Next is a note to remind her about her deal with Coty perfume. The 37-year-old was signed up as the face of the scent this spring.

Then come the words "Songs to Parkinson" – perhaps a reference to tracks she plans to sing on the ITV chat show.

The next note appears to relate to Miss Minogue producing promotional material for a film project.

It is followed by the words "film festivals/release/downloads".

Then "Acting coach number" is followed by "When Dr Who script arriving?" and "Russell's number" – which most likely refers to Miss Minogue's wish to get the phone number of Russell T Davies, head writer of BBC's most recent Doctor Who series.

She is soon to have a role in the sci-fi drama.
