The siblings have had a strained relationship over the years and Liam has now claimed the 'Don't Look Back In Anger' hitmaker is refusing to attend the documentary's premiere.

He wrote on Twitter: "So the Ronnie Corbett of rock n roll aka Noel Gallagher not doing press not attending premiere for oasis film 2 words S**T BAG LG x (sic)"

Meanwhile, the 44-year-old musician previously revealed he only uses Twitter to annoy his older brother.

He said: "Lots of people say I need to chill out about Noel. Not until they stop Twitter. That *** will always get it from me.

"I've heard [my tweets] really annoy him. Someone told me the other week that the only thing that does his nut in are my tweets. Good. They will carry on and they will get bigger and better."

And Liam also claims his brother wasn't even nice about him when they were in Oasis, which subsequently broke up following a row between the brothers in 2009.

He added: "He slagged me off when we were in the same band! He'd do his interview, I'd come in to do mine and they'd go, 'He doesn't like you, does he?' I'd be saying how great he was. He still has pops. He needs to know that I ain't going away."

However, Liam has admitted to missing the Noel he saw when he watched 'Supersonic'.

He said: "I miss the Noel in the film, that's the Noel I know. And I do love him. I don't sit at home crying into a picture of him, though, and I'm sure he doesn't of me either. But I'm an energy and I bet he misses that energy."
