Liam Gallagher claims he is ''fitter'' than his brother Noel's wife.

The 45-year-old rocker has lashed out at his older sibling - who has 17-year-old daughter Anais with ex-wife Meg Matthews, and sons Sonny, seven, and 10-year-old Donovan with spouse Sara MacDonald - after a fan told him the 'Holy Mountain' singer had claimed to have a ''worse'' relationship with his brother than people have with their former partners.

The Brazilian fan tweeted: ''Ah, Noel compared you to a ex-wife, btw.

''I'll explain what happened: he compared you to a ex-wife

The interviewer said: ''so that's the kind of relationship you had?''

And Noel said ''It was worse!!!''(sic)''

In response, Liam posted: ''Cheeky **** I'm fitter than both his wife's (sic)''

Liam's jibe comes after Noel recently claimed the 'Wall of Glass' hitmaker is a ''village idiot'' who he believes is mentally unwell.

The 50-year-old guitarist can't understand why Liam hitmaker decided to publicly hit out him for not performing at Ariana Grande's One Love Manchester charity concert, which was staged a few weeks after a terrorist attack at her show in their home city in May, because he wasn't even asked to appear.

Noel - who recently said Liam needs to seek the help of a psychiatrist - said: ''I will say this - and this is all I will say about it. I don't think that he is well.

''I think it says more about him than it does about anything else. I honestly don't think he is well.

''I don't know where that comes from because we had exactly the same upbringing. Who knows what's inside the mind of a village idiot.''

The 'Wonderwall' songwriter has been embroiled in a long-running feud with his younger sibling ever since Oasis split following a backstage bust-up before a festival appearance in Paris in 2009, which culminated in Liam swinging a guitar at Noel's head.

The pair have several fist-fights during their time in the rock group but the guitarist is adamant that it was Liam who always kicked off the rows and physical altercations.

Noel is adamant he had plans to go solo when he quit Oasis but decided to walk out on the 'Some Might Say' hitmakers because he was done with Liam's constant bickering.

He said: ''I never fought with Liam at all. Liam was fighting with himself. Right now, he is picking a fight with himself somewhere. I don't suffer fools in any f***ing sense at all, but I suffered him more than maybe I should have done.

''I felt maybe, looking back on it, that the stadium rock thing wasn't me anymore. At the time, it wasn't a musical decision. It was literally a case of I can't stand the fighting and the shouting and the firing people for no reason.''
