The 40-year-old made the statement while talking to a teenage fan outside a pub in the New Forest, Hampshire.
The student's impromptu interview was captured on camera and uploaded to YouTube.
Gallagher - who is believed to have been recording and mixing tracks at a studio in the area - can be heard telling 17-year-old Ryan Butterworth that a tour in support of the record is "in the making" and that the band plan to play some UK festivals.
"We're not thinking about it just yet, but we'll definitely be out in a couple of months," he said, before joking that the four-piece would prepare by playing bar mitzvahs.
"We're just working it all out. We've got to make it right this time, last time was a bit f**king stupid," added Gallagher, before dismissing the idea of playing Reading Festival: "We're not doing that f**king thing!"
When Butterworth asked about the band's next LP, Gallagher revealed that it is not in the same vein as its predecessor Different Gear, Still Speeding.
"It's rock and roll, but fired out into space," he said. "If you're into drugs, you'll like it. It's pretty druggy man."
The student described Gallagher - who joked with him about Beady Eye needing a bassist when Butterworth revealed he played the instrument - as "genuinely the nicest man [he has] ever met".
"He was happy to be filmed - he didn't mention it - and he was happy to look at the camera," he told NME.
"He was really down to earth and I stayed with him for about two hours drinking with him. [I was] asking lots of questions. He said he was in the area as he just finished mixing the new album around the corner.
"I am a huge Gallagher fan. I have every record ever. Being a musician there is no-one I look up to more in music."
Earlier this week, Gallagher revealed that he is an unlikely fan of K-Pop star Psy. The singer described the South Korean's smash hit 'Gangnam Style' as "an absolute classic".
