The 24-year-old singer contacted the ex-Oasis guitarist to provide extra vocals on a track for his forthcoming LP 'The Colour Of The Trap' and was delighted when his pal agreed to help.
Miles said: "I texted Noel saying, 'Do you fancy doing these high harmonies? Icing is all it needs.' He replied straight away saying, 'Icing is what I do very well.' "
He said: "When you've been in a band with your best friends like I was, you had your posse around you. But doing this at first was a bit daunting - that whole thing of doing it all, calling the shots."
Miles told GQ magazine: "We are best friends. But I also think there's a bit of competition. If he writes a great tune, then I want to write a great tune. It's healthy for both of us."
