Glastonbury organiser Michael Eavis has said he knows some of the big names who will play at next year's festival - but is keeping them to himself for now.
Michael Eavis has been staging the festival on his farm since 1970
"We do have acts confirmed but I can't tell you," he said, adding that reports of Bruce Springsteen headlining the event in June were "absolute rubbish".
Mr Eavis remained "really hopeful" that Kylie Minogue, who pulled out last year after her cancer diagnosis, would play.
Organisers have said they hope to let up to 20,000 more fans attend in 2007.
This would take the festival's capacity close to 175,000.
Mr Eavis told the BBC News website he was "surprised" to see newspaper claims that Springsteen was in line to play at the event.
But he was "really reassured" by the erroneous reporting because it meant nobody had worked out who the real headliners would be.
"Certainly we hope for Kylie to do the Sunday headlining slot," he said.
Heavy rain and flooding played a major role in last year's Glastonbury
"We're really hopeful she'll do it but it's not confirmed."
In April, Mr Eavis conceded the Australian singer did not necessarily fit the traditional image of his event.
But he added that her theatrical shows were "almost like a circus in a way, which really fits in with Glastonbury".
Last year's festival - with Coldplay, Basement Jaxx and the White Stripes among the stars on the main stage - was the most popular in its 35-year history.
Some 112,500 tickets were sold in three hours, with 40,500 more set aside for staff, media, artists, crew and locals.
The event took a break in 2006 but is due to be held from 22 to 24 June next year.
