British rocker Liam Gallagher has launched a libel lawsuit against his brother Noel.
Noel Gallagher walked out on his brother and their Oasis bandmates in 2009, moments before they were due to take the stage at a gig in Paris, France.
The siblings have since launched a bitter war of words in the press and Noel recently opened up to the press about the incidents leading up to the group's demise, claiming Liam started the bust-up in France by asking to advertise his fashion line Pretty Green in Oasis tour programmes.
The rocker also made allegations his brother pulled out of an earlier appearance at Britain's 2009 V Festival because he was suffering from a hangover - the official statement suggested the singer was suffering from laryngitis.
Now Liam is suing his estranged big brother for libel.
In a statement, released to Britain's The Sun newspaper, Liam says, "I have taken legal action against Noel Gallagher for statements he made claiming Oasis pulled out of the 2009 V Festival Chelmsford gig because I had a hangover. That is a lie and I want Oasis fans and others who were at V to know the truth.
"I was gutted (upset) when I couldn't play the gig because I didn't want to let the fans down. But the truth is I had laryngitis, which Noel was made fully aware of that morning, diagnosed by a doctor.
"Noel also falsely stated the demise of Oasis followed a massive row, in which he claimed I demanded to advertise my clothing range Pretty Green in the Oasis tour programme. The truth is there was no such discussion or row between us.
"I am used to being called all sorts of things by Noel and I have in the past said things about him. But what Noel has alleged this time went way beyond rock-and-roll banter and questioned my professionalism. I tried to resolve this amicably but have been left with no choice but legal action. All I want is an apology."
Noel will now have to make an official response to the writ in London's High Court, and if the brothers still disagree the case will be taken before judges.
It appears Liam has the full backing of his former Oasis bandmates, who are now part of his new group Beady Eye - guitarist Andy Bell recently told the Japan Times that Noel had lied about the reasons for the group's split.
Bell said, "He (Noel) lied about a lot of things. The argument about Pretty Green was lies, what he said about V Festival and the fake laryngitis was lies - I don't know, maybe he's convinced that's the truth. I don't know what goes on in his head. I know him, so I'm not disappointed."
