Liam Gallagher is hardly known as one to hold his tongue.
And as befitting a man once described as 'the angriest man in the world' and 'a man with a fork in a world of soup' by his own brother, he's known for his choice words about fellow musicians.
The former Oasis frontman called out Coldplay lead singer Chris Martin for 'looking like a Geography teacher', described the Scissor Sisters as 'bright colours and fucking weirdos on stilts' and dismissed Florence (of 'and the Machine' fame) by simply saying: "I'm not having someone with ginger hair making music."
True, he may lack the witticisms and repartee of his older brother Noel, and the pair have remained at odds ever since the demise of Oasis in 2009. But in terms of pure playground entertainment, there are few stars out there who can match Liam for shit-slinging alone.
Earlier today, Twitter user Tony Rogers enquired of Liam: "Are you going to see U2 at the weekend? If you are, catch the support act, I'm hearing good things about them."
He was, of course, referring to Noel Gallagher's High Flying Birds, who will open for Bono's rock veterans - Liam replied that he would "rather eat my own shit than listen to them bunch of beige fucks".
He added 'toff rock' in a different tweet, though it isn't clear whether he was slinging mud at his brother or at U2. Knowing Liam, he's probably not that bothered if they both take offence.
The Mancunian singer has had a pop at U2 frontman Bono before.
He previously chided the Dublin-born singer, real name Paul Hewson, for his do-gooding ("Play 'One', shut the fuck up about Africa"), as well as aiming a great many digs at his own brother.
Noel and his band will be supporting U2 on their world tour, which begins in London at the weekend. They'll play at Twickenham Stadium on Friday and Saturday before moving on to Berlin, Rome and Barcelona in the next week.
Liam greeted the news of his rival sibling's support slot with a characteristically nuanced tweet, saying: "I see all that brown nosing is finally starting to pay off," and adding 'NO SHAME' for good measure.
The younger Gallagher has a solo album - his first - due in October and will be touring it, including festival appearances at Leeds and Reading Festivals in the UK, Benicassim Festival in Barcelona and Exit Festival in Serbia, before travelling to the United States and Canada to round out the year.
He rolled back the years at Glastonbury recently, playing a combination of his Oasis classics and more recent tracks, pulled from his Beady Eye project as well as newer solo work.
