The former Oasis star told the Scottish singer that he should 'enjoy his 15 minutes' as well as calling him 'f***ing Chewbacca'.
He made these explosive comments in an interview with Variety. Fifty-two-year-old Gallagher was asked about the war of words between the two, which began when he slagged off Capaldi during a radio interview.

After that incident, Capaldi shared videos of himself celebrating the fact that the Mancunian had acknowledged his existence in his own inimitable style.
Gallagher said: "F***ing Chewbacca should enjoy his 15 minutes.
"The greatest day of his life that I slagged him off or called him an idiot. It's the greatest day of his f***ing life so far.
"He's just thinking, 'Wow!' Well, I know you're Scottish and all that, but f***ing hell! It is like a third world country, but for f***'s sake, man, you must have had a better day than this. Surely!"

It's fair to say that Noel isn't keen on the music of today. After all, that's what got this argument with Capaldi going in the first place.
Gallagher said: "It just seems to me that every singer-songwriter gets to be s****er than the next person. It's a race to the bottom. And you dig deep enough with these c***s, they're not even singer-songwriters, because they don't f***ing write their own songs.
"So, I don't know. The youth of today: f**k*ing moronic c***s, if you ask me. I meet young people, and they're so culturally lost at the moment.
"All they can do, young people, is take pictures of each other. Because there's nothing else. You know, when a band walks out on stage, they might as well be at a photo shoot. Nobody lives in the moment.
"Everybody's sharing everything with everybody."

The interviewer then asked about Noel's daughter Anaïs' comments in support of Capaldi. The 19-year-old model said that she wanted to be Lewis Capaldi when she grows up.
Noel opined: "When she grows up? Well, she better be better looking than that c***!
"Let's hope she doesn't have his looks. Or his girth. I'm not going to allow that. She's gonna have a bad day soon if she wants to be Lewis Capaldi when she grows up."
Well, keep your eyes peeled for Capaldi's latest comeback to this one. All publicity is good publicity, eh?
