Metallica drummer Lars Ulrich asked Noel Gallagher to sing at his wedding.
The heavy metal icon is a huge Oasis fan and became firm friends with the 'Wonderwall' hitmaker after they met in the mid-90s.
Lars, 52, was desperate for Noel to serenade him and model Jessica Miller when they tied the knot but the 48-year-old musician refused to be a wedding singer for one night.
Speaking as he hosted a special show for Absolute Radio - which can be listened to at Absoluteradio.co.uk - Noel said: "Lars is great you see. He's a huge Oasis fan. And he's a friend of mine.
"The first autograph I ever signed on American soil was for Lars. I didn't even know it was him. He said, could you make it out to Lars Ulrich and I wasn't looking at him. I said, what the drummer from Metallica? And he went yeah. And I looked and there he was. I was just like, god.
"I love Lars. I speak to him irregularly quite often. He asked me to perform at his wedding. I declined that - that was a bit weird. But he's a good lad Lars."
Lars has always been fulsome in his praise for Noel - who was in Oasis with his brother Liam Gallagher before quitting the group in 2009 - and his talents as a songwriter.
The 'Enter Sandman' rocker previously revealed Oasis has been the "soundtrack" to his life.
Lars said: "Oasis has been the soundtrack to my life for the last 20-plus years on this wonderful planet. 'I have stories and pictures in my mind that go along with everything, from the first time I heard particular songs and read certain articles, to hearing about the band's shenanigans and festivities.''
