*Word has it that Beyonce is set to join Coldplay and U2 as a headliner at U.K. music festival Glastonbury.

Chris Martin’s band were confirmed on Monday (Feb. 7) as one of the big acts to hit the stage at the three-day event in June, while U2 have long been linked to a top slot at this year’s festivities after Bono’s back injury forced the Irish rockers to pull out of the 2010 event.

The full official line-up has yet to be unveiled, but founder Michael Eavis recently revealed, “There’s an American artist that I’ve been wanting to have for years.”

For some reason, UK gossip blogs, including website HolyMoly.com, believe this mystery star is Beyonce.

If the rumors are true, it would be the Bey’s first performance at Glastonbury. She previously attended the festival in 2008, but only to support her husband Jay-Z as he headlined the traditionally-rock event.

A spokesperson for Beyonce has yet to comment on the reports.
