Pop star George Michael is considering a £50 million offer for Damien Hirst's diamond-encrusted skull.
The singer and his partner Kenny Goss were given a private viewing of Hirst's work last week.
Covered in 8,601 diamonds, the work - entitled For the Love Of God - is the world's most expensive piece of contemporary art.
"Michael and Kenny took in a private viewing of the diamond-encrusted skull. They looked at the piece as a possible addition to their collection," a spokesman for the couple said.
The former Wham! star, who became the first singer to play the new Wembley Stadium on Saturday, is a fan and collector of Hirst's work. He and Goss already own Saint Sebastian, Exquisite Pain, the body of a black calf pierced by dozens of arrows and tied to a steel post.
The couple's art collection is currently valued at £100 million, according to the spokesman.
Later this month they will launch the Goss-Michael Foundation, a non-profit organisation dedicated to promoting and inspiring young artists.
Michael is not the first buyer to approach London's White Cube gallery about Hirst's headline-grabbing work.
The artist bought the skull from a shop in north London and it is believed to date from the 18th century. The diamonds are worth £12 million and weigh 1,106.18 carats.
Hirst said of the skull: "I hope it makes the people who see it feel good, that it's uplifting, that it takes your breath away."
