Gallagher also rubbished recent stories saying Oasis were ready to "do a Prince" and have a residency at London's O2 Arena.
"We'll never play the O2," he said. "We went there to see Led Zeppelin and to be honest the gig was fantastic, but it was the most soul destroying venue I've ever been to.
"And much to our manager and agent's disappointment, we came back and said we would never play there.
"So it means we are going to have to do 640 nights at Earl's Court, I would have thought.
"It's too Americanised for me, and it's too far away. Any gig you can get to by boat that hasn't got a beach is wrong."
He did confirm that Oasis' seventh studio album had been completed.
"That's finished. All done. We're just kind of waiting to get a record deal and get it out.
"We've not managed to get a title yet. We're in the middle of doing the artwork. Down to a shortlist of about three."
