The Gallagher brothers have been embroiled in a bitter feud for almost as long as they've been famous.
But now it is reported that their ongoing fallout has hit a new low as their children publicly choose sides.
According to The Sun, Liam's son Gene, 22, whose mother is Nicole Appleton, ignored Noel at a VIP bar at Glastonbury, even though they were just yards apart.
A source told the outlet: “Noel and Gene clocked each other but kept well apart.
“It was quite sad to see given they are so closely related but there is still a lot of bad blood between Noel and Liam.
“They were only standing 20 yards apart but neither of them would break rank to say hello.”
The Standard has contacted Gallagher’s rep for comment.
It was reported that Noel partied until 3am at the festival on Sunday after watching the Irish band Kneecap in Shangri-La.
Last August, Noel had to make a quick exit from Chiltern Firehouse restaurant with his daughter Anais when Gene’s brother, Lennon, showed up. Lennon's mother is Patsy Kensit.
The awkward run-in follows Liam responded to reports of a supposed Oasis reunion tour with Noel, allegedly booked at London's Wembley Arena for July 8, 9, and 10.
Last week, the 51-year-old singer clarified that he was unaware of any such plans when questioned by a fan on X, formerly known as Twitter.
The social media user asked: “Liam is Oasis reunion next year actually happening?”
To which, the musician joked: “Nobody’s told me maybe there getting a new singer like the dude out of queen.”
Liam and his brother Noel, 57, have been in a public feud since Oasis split at their last concert in Paris in 2009 following a backstage altercation.
Despite earlier reports of booked dates at Wembley, the anticipated reunion gig has been cancelled, reportedly due to the brothers.
A source told The Mirror: “An Oasis reunion has been hoped for for years. This year would have been the big moment, 30 years on from their debut album Definitely Maybe,' a source said.
“But until now, no one has known how close Liam and Noel came to making it a reality.
“It doesn't get much closer than booking Wembley, and their teams were devastated when it all collapsed yet again.”
