EX-OASIS singer Liam Gallagher has attacked his brother Noel, questioning his singing and calling him a "fake".
Oasis split in 2009 just as the band was about to go on stage, and Liam has frequently criticised Noel in the years since.
Now Liam, 44, who is releasing a new record, has launched a Twitter rant against his older sibling.
In another dig, seemingly directed at his lifestyle, Liam also wrote: "See the fake bombing about in his stone island again coz he's in [Manchester] he'll be back in his Prada 1st thing tomorrow".
And then, for good measure, he declared himself better than Noel: "Opening with Don't look back in anger ending with Rocking chair bout time they were done proper LG not for sale".
Liam said he will be playing Oasis hits such as Don't Look Back In Anger on his tour, adding: 'I can and will sing any song he wrote bigger, better than him even if I was kicked in the bollox by a wood pigeon'.
Liam insisted his older brother only wore his parka jacket in the city because the item of clothing is famous for being worn by the locals and Noel - who has lived in London for 20 years - is apparently keen to impress them. Bieber responded with a non-apology apology, tweeting "sorry i didn't bow down to you".
