Sir Paul McCartney considers himself a "playaholic", because he never thinks of his music career as work.

The Beatles legend was chatting to Zane Lowe in an interview for Apple Music when he reflected on being considered a "workaholic".

He said: "People say, 'Oh you're a workaholic' and I say, 'We don't work music, we play it, so I'm a playaholic!

"I hate it when making music starts to feel like work."

Zane then remarked that music producer Brian Eno had made an "almost identical" comment in a recent interview with him.

To which Paul, 83, said: "I saw your thing about Brian Eno and he says this, he says this thing about 'playtime' and I go 'that's… he's nicked it, he's heard me say it!'

"Because I'm always saying that! He's taking all my lines, this guy!"

Later in the interview, Paul once again ignited his "beef" with Brian as he laughed he had also heard him talking about "tape loops" - where magnetic tape are spliced end-to-end to play continuously.

Paul said: "I like to work with tape loops and again Brian Eno… in your interview, he starts talking about tape loops.

"And I'm thinking, 'Brian! You're nicking all my ideas!' Tomorrow never knows, it was before you were born!"

Zane responded: "This is a serious celebrity death match we've got on our hands right here between the two of you."

With Paul hilariously putting on a threatening voice as he looked to the camera and told Brian: "If you're listening!"

Elsewhere in the interview, Zane asked Paul if he regrets not having reunited with his Beatles bandmates after their split to make more music.

To which Paul replied: "We knew we'd finished. And we'd all said it's full circle, this is great.

"John (Lennon) was off on his life with Yoko (Ono) which was… you couldn't say 'Would you mind coming back and we'll do a bit more Beatles?'

"I wouldn't have put that to him. I could see what he was doing, it was a different life, and I was too with Linda."

John met Yoko at an art gallery in 1966 before they began an affair, which led to John leaving his first wife Cynthia for his mistress. He and Yoko married in 1969, with The Beatles announcing their split the following year - which led to speculation Yoko may have been responsible for the band breaking up.

Paul was married to Linda McCartney for 29 years until her tragic death in 1998 when she lost her long-running battle with breast cancer.
