Liam Gallagher is said to have clashed with actor Idris Elba at an after party following the NME Awards on Wednesday (February 27).
According to The Sun, the Beady Eye frontman picked a fight with Elba while attending a bash at London's Ivy Club - poking fun at the Wire star's bobble hat.
An onlooker told the tabloid: "Liam was in full rock'n'roll swagger mode. He bowled up to the party after midnight and made his presence felt pretty quickly.
"He had a row with a Scottish actor called Martin Compston, mocking his accent."
They continued: "Then he had a few words with Idris, poking fun at his bobble hat among other things. Idris looked like he was going to flatten him - they were on completely different wavelengths.
"They were toe-to-toe at one point. Neither of them backed down. Idris was in a good mood, so left it, which was probably for the best. Liam left soon after."
