Liam Gallagher has accused his older brother Noel of being fake in a Twitter tirade.
The outspoken rock star, whose on/off feud with his chart-topping sibling is legendary, has slammed Noel for supposedly behaving in a way that wasn't genuine during a recent trip home to Manchester, England.
He wrote: "See the fake bombing about in his stone island again coz he's in manc he'll be back in his Prada 1st thing tmorrow LG X (sic)"
Liam, 44, was referring to Stone Island, the clothing company known for their parka jackets, which he claimed Noel had started wearing on his return to Manchester in order to fit in with the locals.
Liam subsequently took aim at Noel's music career, referring to the Oasis tracks 'Rockin' Chair' and 'Don't Look Back in Anger', and claimed he is more talented than his elder brother.
He wrote on the micro-blogging site: "Opening with Don't look back in anger ending with Rocking chair bout time they were done proper LG not for sale.
"To all you NG fanboys I can and will sing any song he wrote bigger better than him even if I was kicked in the b****x by a wood pigeon LG (sic)"
Liam ended his tirade by telling Noel's loyal fans that he hopes his new album, 'As You Were', would send them "mad".
The rocker, whose first single from the album is to be called 'Not For Sale', said: "To the people who dig what I'm about I know you'll freak out as its proper to the people who hate what I'm about I hope it sends you mad LG (sic)"
Oasis split in 2009 just as the band was about to go on stage, and Liam has frequently criticised Noel in the years since.
In 2016, for instance, he labelled his elder brother a "yes man" and a "potato".
Noel, on the other hand, admitted in 2015 that the last six months in the band were "f***ing awful".
The 49-year-old star previously shared: "It was excruciating. Me and Liam had a massive, massive, massive fistfight three weeks before the world tour started.
"And fights like that in the past would always be easy to rectify but for some reason I wasn't going to let it go this time. I was just like, 'F**k this ****.' And there was an atmosphere all the way around the world."
