If tabloid sources are to be believed, Prince could be topping the Glastonbury Festival 2011 line-up when the event it returns to Worthy Farm, Somerset from 22-26 June.
Following their cancellation last year, U2 are set to top the bill as well, with Coldplay currently in talks about making their first appearance since 2005, reports in the Sun claim.
A source told the newspaper: "Michael was very keen to get the line-up sorted early and is over the moon at securing such massive acts. He is a huge fan of Prince and has been trying to nab him for years.
"The fact it's been tied up so quickly is a big but welcome shock."
The source added: "Coldplay are currently in negotiations about taking a headline slot.
"Michael has previously said Coldplay's set in 2005 was his personal favourite and is very pleased to be welcoming them back.
"U2 were a fairly obvious capture. Michael immediately had his sights set on them after they were forced to cancel this year and they were very happy to oblige."
A spokesman for Glastonbury Festival refused to comments on the claims. They said: "We never comment on rumours until the official line-up is announced."
Beyonce is also among the Glastonbury Festival 2011 rumours, but according to reports from the US the singer is pregnant, which could rule out her appearance.
