Kings Of Leon want to make a song with Taylor Swift.

The 'Sex on Fire' hitmakers' frontman Caleb Followill has revealed he has been a close pal of the 26-year-old 'Shake It Off' singer for some time and he has teased that they may have already been in the studio together.

He said: ''I've been a friend of Taylor Swift since she was young. I wouldn't be surprised if we hadn't already written together.''

It comes after the pop beauty attended their surprise concert at New York's Le Poisson Rouge lounge last month.

Meanwhile, the 34-year-old rocker - who is married to Victoria's Secret Angel Lily Aldridge, 30 - has poured cold water on rumours the indie rock group are performing at next year's Glastonbury Festival at Worthy Farm in Somerset, South West England.

He told the Daily Star newspaper: ''We'd love to but I think they're booked up now.''

Caleb - who is joined by his brothers Nathan Followill and Jared Followill and their cousin Matthew Followill in the group - previously said he was planning on phoning up the iconic music extravaganza's organiser Michael Eavis to get them on the bill, before learning they were fully booked for next year.

He previously said: ''We love Glastonbury.

''I think that was the first festival we played in Europe. Do they still do it where it's on one year, off one year to the grass grow? ... OK, then we'll have to get on it in 2017. I'll have to text Mr Eavis.''
