Don't is rumoured to be about high-profile ex-lover Ellie Goulding.  According to The Mirror newspaper, The 23-year-old Glastonbury headliner admitted he was worried about how the mystery woman would react even though he forewarned her.

According to Ed, he  said to her, 'just so you know, there is a song.' And they said, 'I expected that.' You know, I didn't lie at all. It's 100 per cent true ... I don't hold grudges. I'm completely over it. I'm fine with the situation. It was just quite an insulting thing at the time. And I felt the need to express myself I guess."

Ed performs this song using loop pedals - so he basically loops himself over and over - his Glastonbury performance was a completely solo one but he filled the stage with his music - and he had the crowd stripping off and swinging their clothes in the air!

He admitted to being very nervous because he had to follow Dolly Parton - but he didn’t seem it on stage.

He also joined Rudimental on stage for their collaboration 'Bloodstream' which features on new album X.

The album X has gone straight to number 1 in Ireland and the UK.
