The 'Angels' singer claims he has seen UFO's on multiple occasions.

The 50-year-old performer said he believes that life from other planets want him to be their messenger, and that they are trying to communicate with him so that he can speak on their behalf to the world.

Williams claims that he has had several extraterrestrial encounters over the years, both while living in the UK and in Los Angeles, where he currently resides.

Speaking to 60 Minutes Australia, the Stoke-born singer cited one particular example of his otherworldly contact, which occurred while he was in a recording studio writing the song Arizona.

Speaking to host Liam Bartlett, Williams said: I've seen a few strange things. I've experienced phenomena that I can't explain.

"It's intriguing and it's powerful," he continued.

When asked if he believes in UFO's, he replied: "I believe in the mysteriousness. Whatever they are I don't know but I've seen one, you know?

"I've seen one right above me and if I had got a tennis ball out, I could have hit it with a tennis ball.

"No substance was involved," he clarified.

Williams lives in Beverley Hills with his wife Ayda Field, and their four kids; Teddy, 11, Charlie, 9, Coco, 5, and Beau, 3.

The former Take That member said that he believes the aliens are contacting him because of his pop star status.

"I sometimes think - and I try to separate narcissism and ego, unsuccessfully a lot of the time - but there's lots of different theories that we all have to do with this stuff but I often wonder if I'm supposed to see it because of my public platform," he said.

"Am I supposed to see this so I can talk about it?"

While he disclosed that several of his strange encounters took place in the UK, he believes that Los Angeles is a location that attracts visitors from other planets.

"For some reason, I feel closer to the woo-woo in Los Angeles than I do in England," he said.

"I had a house in Wiltshire, the grounds and the house were a thousand years old and you would think that there I would be inundated with spectres or doors slamming, other people experienced it, but I didn't. It's not until I go to Los Angeles where I live, or lived for a while, that it's like there's vortexes here, it's a very strange land."

Williams expanded on his most memorable encounter with creatures of another kind, which occurred in a recording studio in 2008.

"I'd just written a song called Arizona, and it's all about alien contact and I was playing that.

"I stood on the balcony and there was this big ball of gold light that turned up - we thought it was Venus or Mars or something," he added.

"Then the song stops playing and it disappears. But then we put Arizona on again and the ball turned back up. It happened four times. After that a massive electrical storm started and these two big massive balls of light started dancing in the sky. It was like a whole light show for about an hour."

In the same year as this experience, the Rock DJ singer was involved in a documentary with British-American journalist and filmmaker Jon Ronson.

The pair ventured to Nevada to attend a UFO conference and, over the course of the film, meet a variety of extraterrestrial experts.

The unlikely duo meet a doctor who claims to have 15 metallic objects which are not earthly, as well as a British woman, Ann Andrews, who believes that her youngest son Jason is an 'indigo child' - a child abducted by extra terrestrials while in the womb and sent back to Earth to save the planet. 

Williams was back in the limelight last year, when he released a documentary series on Netflix, which charted his rise to fame as a member of Take That, before being catapulted into a successful solo career.
