Noel Gallagher has taken another swipe at his ex-bandmate brother, saying that Liam's Glastonbury set "embarrassed" him.
Liam Gallagher, the 46-year-old Mancunian, performed solo hits at the iconic festival, as well as some Oasis classics.
However, speaking to The Guardian, brother Noel said: "I don't think I've ever been so embarrassed for a man in my entire life.
"He's pulled off the incredible magic trick of making those Oasis songs sound weedy and thin.
"And he looked like he was having the worst day of his life, walking around in what looks like a pair of my son's pyjamas, shouting into a mic about some perceived injustice… if you can't sing 'em, don't play 'em!"
Oasis dramatically split in 2009 after a backstage fight at a French music festival just minutes before they were due to perform.
Since then, Liam and Noel have spent a decade taking aim at each other, putting to bed any remote hopes of a reunion for the 90s Britpop band.

Noel even went as far as saying he "liked [his mum] until she gave birth to Liam".
Talking about his brother's new music, Noel said: "I reckon if I put my two sons [aged 11 and nine] in a room… for about 45 minutes, they could probably muster up something better than that new single of his."
Last month, Noel accused Liam of sending "threatening messages" to his 19-year-old daughter.
