The Last Shadow Puppets singer was asked to play the warm up slot for the band's recent concerts and although he had met Liam before, Miles was still surprised with the level of support he got from the singer.
He told Shortlist magazine: "I think their management got in touch after they heard the songs 'Inhaler' and 'Come Closer'. I'd met Liam in a bar once before when we had a chat and a fag, so I didn't really know him but it was great to be asked and they really enjoyed having us. Liam was watching each performance from the sides.
"I actually only met him very briefly on the tour. I was waiting to go on stage on the first night in Glasgow and he came out of his dressing room and walked straight over to me. Then he just grabbed me and went, 'I f***ing love you and I love 'Come Closer'. It was great."
Miles also claimed he admires the Beady Eye frontman so much that he would love to be him but knows he and others could never compete.
He explained: "Liam Gallagher is the only person who can be Liam Gallagher. Lads try to be like him - we all grow our hair the same and have that swagger - but you've got to leave that stuff to Liam. Sometimes we all like a little rant but you've got to be yourself."
