Adele is in talks to headline Glastonbury.

The 26-year-old singer - who has previously insisted she ''will not do festivals'' - has been wanted by festival organisers Michael and Emily Eavis for years to top the bill at the music spectacle this summer, and the pair are reported to be closer than they've been before to signing her up.

A Glastonbury source told the Daily Mirror newspaper: ''Most of the acts have been booked for Glasto but Michael and daughter Emily Eavis are still trying to get Adele for Saturday night.

''She has been on their wishlist for a few years now. Negotiations are ongoing but this is the closest they have got to signing her.

''Several bands that have been booked for Saturday have been told they could be performing before her. It's created quite a buzz.''

Emily has previously publicly revealed her desire to sign Adele for the event in Somerset, south west England - which this year takes place from June 24-28 - and while the singer hasn't played a full gig since September 2011, before giving birth to her son Angelo in October 2012, the organisers are ''determined'' for her to headline this year.

The source added: ''Emily and Michael know what a big deal this would be and they are determined to make it happen.''

A festival spokesman said: ''We look forward to announcing the line-up in the late spring.''

Michael previously revealed the three headliners will be announced on April 1 and despite admitting one has ''been around for a long time'', he ruled out the possibility of Queen or Fleetwood Mac taking to the famous Pyramid Stage.

Another act who also looks unlikely to play Glastonbury is Taylor Swift as her good friend Ed Sheeran recently insisted she is not a big fan of festivals.

He said: ''Taylor doesn't like festivals.

''So for any bookies reading ... I think Taylor likes doing her own show because she's in control and it's how she wants it to be.''
