Paul McCartney has revealed that he and late Beatles bandmate John Lennon once indulged in group masturbation during their rise to fame — while fantasising about pin-up Brigitte Bardot.

In a revealing interview with GQ magazine, the legendary rocker, 76, admitted that he and a small group of friends spent some time at John's home, when they all decided to pleasure themselves in front of one another.

He recalled: 'And instead of just getting roaring drunk and partying — I don't even know if we were staying over or anything — we were all just in these chairs, and the lights were out, and somebody started masturbating, so we all did.'

Revelation: Paul McCartney has revealed in a new interview with GQ magazine that he and his late Beatles bandmate John Lennon once indulged in a group masturbation session — while thinking of screen siren Brigitte Bardot

Paul explained they were encouraging each other on by shouting out names to help them stay aroused.

He recalled: 'We were just, "Brigitte Bardot! Whoo!" And then everyone would thrash a bit more'.

However, the mood was killed when Lennon shouted Winston Churchill’s name as a joke.

Paul continued: 'There’s so many things like that from when you’re a kid that you look back on and you’re, "Did we do that?" But it was good, harmless fun. It didn’t hurt anyone. Not even Brigitte Bardot.'

Activity: The legendary musician admitted that he and a small group of friends visited John Lennon, pictured right in 1963, at his home, where they spontaneously enjoyed the activity

And the revelations didn't end there, as Paul responded to a quote from John, who was murdered outside his New York City home in 1980, which read: 'There was nothing about orgies and the s**t that happened on tour'.

Paul candidly admitted: 'There weren't really orgies, to my knowledge. There were sexual encounters of the celestial kind, and there were groupies.'

Talking about his own raunchy past in the band, he admitted to having a threesome with two prostitutes in Las Vegas but said orgies 'weren't [his] thing'.

He said: 'There was once when we were in Vegas where the tour guy, a fixer, said, "You're going to Vegas, guys—you want a hooker?" We were all, "Yeah!" And I requested two. And I had them, and it was a wonderful experience. But that's the closest I ever came to an orgy.'

During the interview, the British musician opened up about his unusual writing sessions with Kanye West and his regret over Amy Winehouse.

In 2015, Macca landed his most successful single on the US Billboard Hot 100 since 1985 with Kanye West and Rihanna collaboration, FourFive Seconds, which peaked at number four.

He and West first met in 2008 at the European MTV awards in Liverpool, where he said the pair bonded over their recent failed romances

He said: 'I'd just gone through my divorce, and I was kind of a little bit raw from it, and I said something to him about it, and he'd just broken up with someone, and he just pulled out his phone and played this great little track.'

Six years later, Paul received word that Kanye wanted to write with him, which he agreed to only if it was kept secret.

They met in a bungalow round the corner from the Beverly Hills Hotel in Los Angeles, with Paul admitting he found the writing sessions 'puzzling.'

Revealing Kanye creates an 'ingredient pool' rather than writing a song in the traditional manner, the pair talked a lot, with Macca playing a little piano and acoustic guitar.

Going away thinking they hadn't 'really done anything' but that Kanye was 'a very interesting guy', Paul didn't hear anything for months, before results began to filter back to him.

The first song was Kanye's tribute to his mother, Only One, but the second song, FourFive seconds left him confused.

The Help singer said he loved the song but had to call to ask whether he was on it.

It soon emerged the riff forming the centre of the song, was a piece he had played on acoustic guitar which had been sped up and raised in pitch.

He also realised the similarly high-pitched backing vocals were also him.

Unusual: The pair co-wrote worldwide hit FourFive Seconds but Macca admitted he had to ask if he was on the track after some unusual writing sessions

When asked: 'Did you have to ask someone what 'four five seconds from wilding' meant? Macca responded: 'Wilding,' yeah,' he says. 'But my stepson knew. He's up with the hip-hop talk: 'Wilding? Oh yeah, that's like getting crazy and stuff.''

He paid tribute to Rihanna, saying: 'I mean, Rihanna is something else. She's cool. So it was a great thrill, actually. I loved it. I feel a kind of privilege that they think I'm worthy of their world. I know I'm worthy of my world, but I didn't know that they think I could fit.'

The Wings frontman took a candid look back at his early days in the Beatles, including the steamy antics the group used to get up to with fans back in the day.

Speaking about other vices in the band, Macca said he was the last of the 'Fab Four' to take acid, but admitted he would not be tempted now.

Regret: The Let It Be hitmaker said of Amy Winehouse: 'I knew she had a problem, and I ended up just saying hi, she said hi, but afterwards I thought I really should have just run after her—'Hey, Amy, listen, you're really good'

He said: 'Well. I was asked just the other day, and I thought, 'You know what, I've got the grandkids and stuff. There's enough going on. I'm okay.''

He added: 'I'm not ruling it out.'

Talking about the writing process for many of the band's hits, which he went through with John Lennon, he said: 'We never came away from a writing session dry. No matter how many hours we spent together writing, we always came away with songs.'

Opening up about one of the band's iconic songs, Paul said he had woken up one day with the melody in his head.

Unable to think of words, he humorously revealed the tune was known as 'scrambled eggs' for some months after he had blocked out the chords.

The Let It Be hitmaker also spoke of his regret when meeting Amy Winehouse in 2008, three years before her tragic death

He said: 'I knew she had a problem, and I ended up just saying hi, she said hi, but afterwards I thought I really should have just run after her—'Hey, Amy, listen, you're really good, I really hope you…'—and say something that broke through the despair.

'And she'd remember and think, 'Oh yeah, I'm good, I've got a life to lead.' But you always have those little regrets.'
