The Oasis reunion tour gets underway later this week, and soundchecks are already happening.
But Liam Gallagher, 52, has denied that vocals heard from the Principality Stadium in Cardiff earlier this week were his.
Fans were able to hear Cigarettes and Alcohol playing from the venue on Monday - which lead some to believe Liam was singing with his brother Noel.
But replying to a video of the soundchecks, he wrote on X: “Mmm I’m not sure about the vocals there too aggressive he really needs to take a chill pill man he’s just so angry all the time I don’t know who he thinks he is as far as I’m concerned he’s just a bigmouth from up north.”

A fan then asked Liam to confirm whether or not he was singing - to which he had a funny reply.
“I've been in my pool all day doing under water farts so it’s defo a recording from rehearsals unless there’s 2 of me which I’m absolutely 1 million per cent here for well there for as well,” he said.
The Oasis Live ‘25 tour kicks off on July 4 in Cardiff and boasts 17 dates around the UK and Ireland.
The brothers will hit stadiums in Cardiff, Manchester, London, Edinburgh and Dublin before going global with shows in Japan, Argentina, the United States and Brazil.
Speaking to talkSPORT Breakfast with Jamie O’Hara and Jason Cundy last week, Noel shared an insight into the Britpop legends’ tour preparations.
“We finished rehearsing last Tuesday. We've got a few days off now and it's sounding huge, so we're all, ‘well this is it, there's no going back now’. It's good,” the rocker, 58, said.
Liam and Noel famously feuded for years, with Oasis splitting in 2009 following a backstage row at the Rock en Seine festival in France.
They announced their reunion tour in August after years of their loyal followers pleading with them to get back together.
The Wonderwall rockers have 41 dates booked in total for their 2025 tour and will be joined onstage by acts such as The Verve’s Richard Ashcroft, Cast, Cage The Elephant and Ball Park Music.
