AceShowbiz - British festival mogul Michael Eavis has sparked rumors he's landed Prince as the prestigious headline act for next year's Glastonbury. Eavis admits he is delighted after inking a deal with an iconic American musician to top the bill on the Sunday night of the famous event in Somerset, England next year.

He has refused to confirm the identity of the headline act - but music industry insiders are adamant the mystery guest is either Prince or "Like A Virgin" legend Madonna. Eavis tells Britain's Heart Radio, "We've got two out of three headliners already sorted. There's American artists that I've been wanting to have for years and yonks (ages)... so it's confirmed. I can't tell you who it is. I really cannot tell you who it is!... It's so good though, I'm so thrilled about it."
