Country icon Dolly Parton is set to make her debut at Britain's Glastonbury festival, according to a U.K. report.

Festival boss Michael Eavis revealed earlier this year (13) that he had signed up three headliners who had never played the event before, sparking rumours Prince and Madonna were set to grace the stage in June (14).

Now editors at Britain's The Sun report Parton will perform on the main Pyramid stage on the event's Sunday night slot.

A source says, "It is being kept free deliberately. She'll get a helicopter straight down on Sunday, or maybe even Saturday night after the show."

Glastonbury will run in Somerset, England from 25-29 June.
