Kanye West was ''depressed'' after forgetting the lyrics at Glastonbury Festival.

The 39-year-old singer songwriter forgot the lines to his 2007 hit 'Stronger' during his performance at the annual music festival in Somerset, South West England, last year and likened the embarrassing moment to being unemployed and couldn't afford a haircut.

Speaking about the moment on BBC Radio One on Monday (01.08.16), he said: ''It was incredible. I started off the show and I completely messed up the music. And me, as you can imagine by this phone call, I'm a bit of a perfectionist.

''So it really put me into a slightly depressed state and it put me back in the position of when I was in high school and I got fired from my job, or when I played my music for R. Kelly and he told me he was going to sign me and then three months later I didn't have any money I couldn't afford a haircut, I couldn't take my girlfriend to the movies and I'm still in my mumma's bedroom, working on beats and I was that close to being signed by R. Kelly...''

And the father of two - who has three-year-old daughter North and seven-month-old son Saint with his wife Kim Kardashian West - admitted he never feels nervous before going on stage, except for this gig.

He explained: ''I don't usually get nervous, I prepare, I get fully prepared. When that music messed up in the beginning it tapped into my nerves and when you're nervous or vulnerable something special and something different can happen.''
