Jay-Z was the main act at the Glastonbury Festival in June
Jay-Z has performed a song on stage in New York criticising Noel Gallagher over comments he made about the rapper headlining Glastonbury.
The musician, in a surprise appearance at a Kanye West concert, rapped about "that bloke from Oasis".
Gallagher caused a stir when he told the BBC in April that a hip-hop headliner was "wrong" for the festival.
The guitarist has played down his comments saying they were "taken wrong" and called for an end to the spat.
Jay-Z's performance continued with lyrics about Gallagher claiming that the rapper could not play the guitar.
"Somebody should have told him I'm a rock star," he rapped before using a line from the Oasis hit Wonderwall.
Jay-Z's unnamed track is expected to appear on his forthcoming album Blueprint 3.
Gallagher has complained that the amount of attention his Glastonbury comments had received was "ludicrous".
The musician told NME magazine: "I wasn't saying I was better than Jay-Z as a person or rock was greater than hip-hop as a thing or whatever it is."
In an interview with the BBC's Colin Paterson in April, Gallagher said: "Glastonbury has a tradition of guitar music... I'm not having hip-hop at Glastonbury. It's wrong."
