Prince is reportedly in talks to play a surprise set at Glastonbury festival this week.

The 'Raspberry Beret' hitmaker, who was rumoured to be headlining the event at Worthy Farm, was ruled out after Metallica, Kasabian and Arcade Fire were announced but sources claim he still wants to surprise festival-goers at the event in Somerset.

A source told The Sun newspaper: ''Prince wants to show up somewhere as a surprise. He has spent so much time in the UK lately, he'd love to do an impromptu set.''

Organiser Michael Eavis and daughter Emily previously said Prince would not be playing the festival this year but they still hope to book him in the future.

The 56-year-old musician, who was bookies' favourite the headline, has been touring the country for the past couple of months with his all-girl female rock band 3RDEYEGIRL.

Meanwhile, Metallica were reportedly in talks to cover a track by the 'Purple Rain' singer but frontman James Hetfield was against the idea.

The source added: ''There was the suggestion of them covering Prince, reminiscent of when Jay Z came on to Wonderwall [by Oasis], but it got a firm, 'No', mostly from singer James Hetfield.''

EE has installed a bespoke 4G network and card readers for contactless payments at the event this year and the 'Highspeed Herd' will bring festival-goers superfast WiFi. The cows were painted by legendary bin painter, Hank, who has decorated thousands of colourful bins for the festival since the '80s.
