Liam Gallagher has threatened to reignite a "war" with Damon Albarn and his brother Noel for collaborating on a new Gorillaz album.
The former Blur now Gorillaz singer invited former rival Noel Gallagher to lend his vocals to one of the band's new tracks.
We Got The Power featuring Noel and Savages' Jehnny Beth is part of Gorillaz' latest album Humanz, released on Thursday.
Oasis and Blur were Britpop rivals in the 1990s, before the two Gallagher brothers had a high profile fallout.
"Now that d*** out of Blur and the creepy one out of Oasis need to hang their heads in shame as it's no Dancing In The Streets - as you were," Liam tweeted on Thursday, following the album's launch.
"That gobs**** out of Blur might have turned Noel Gallagher into a massive girl but believe you me, next time I see him there's gonna be war," he added.
Noel and Albarn were asked about burying the hatchet and not inviting Liam, to which Noel answered: "Listen, nobody gives a f*** what Liam thinks about anything."
"I mean now it feels like, completely, you know, not news at all really," Albarn said.
"He's fantastic in the studio and it's nice when you see how someone goes about their business."
Last month, Liam Gallagher was announced to headline the Reading & Leeds festival with his latest album titled As You Were.
In a series of tweets, he said he would be playing old Oasis songs "bigger and better than Noel".
"Opening with Don't Look Back In Anger," he wrote.
"To all you Noel Gallagher fanboys I can and will sing any song he wrote bigger and better than him even if I was kicked in the b***** by a wood pigeon".
