The feuding siblings have had little contact since the guitarist quit Oasis in August 2009 and the 'AKA...What A Life' hit maker insists there is no chance of repairing their relationship after the Beady Eye front man tried to sue him when he claimed they pulled out of a gig because Liam was hungover.
He said: "Once someone sends you a f***ing lawyer's letter accusing you of - what was it? It was so laughable, I didn't respond to it, until I had to, by law. He was accusing me of 'destroying' his brand. If such a thing exists, then f***ing hell, what's the world coming to?
"So now, I don't speak to him. The last time I saw him was at a party after the Olympics, and as usual he hurled some insult at me and off he went. I'm better off not speaking to him."
Noel was asked to be a part of the London 2012 opening ceremony, but decided not to be involved, though he insists he doesn't mind the fact Liam and Beady Eye stepped in to perform the segment he had initially been offered.
He said: "I'm afraid I didn't make Team GB in the end. The whole thing was choreographed and they asked me to do 'Wonderwall' acoustically. I mulled it over and then they said, 'You can't do it live?' Why not? 'Well, it's a big gig.'
"Finally, I said, 'You know what, I'd rather watch it on the telly.' But they'd got so far down the line with choreographing 'Wonderwall' in that, I was like, 'Fine, get someone else to do it, just not the f***ing Kaiser Chiefs...' So they went to Liam's lot and I was absolutely fine with it. Not arsed."
