Noel Gallagher has called his brother Liam a "squeaky toy that swears a lot" in a mocking interview on British radio.
The pair, who fronted Brit-rock band Oasis, are known for the constant in-fighting which led to the group's 2009 split.
They talked for the first time since the band's break-up amid their mutual jubilation at their beloved Manchester City football club's premiership win in May.
But in an interview with BBC Radio 6 last week, Noel showed the relationship had not thawed completely.
He told host Shaun Keaveny even their mother could not stop them fighting.
