Robbie Williams could be abducted by aliens any day and become an ambassador for their race.

The pop star is a "point man" for extraterrestrials and will soon start a new religion in their honour, according to the director of the New York Centre for Extraterrestrial Research Michael C. Luckman.

Luckman – the author of 'Alien Rock: The Rock 'n' Roll Extraterrestrial Connection' – has been following Robbie, 34, closely as he has devoted more and more time to UFO-spotting and says he is sure aliens are using Robbie as their representative on Earth.

He told BANG Showbiz: "Robbie is now becoming a point man for contact with extraterrestrials. None of the experiences I've seen are in the same category of what Robbie appears to have experienced. Robbie could easily disappear and then come back as an ambassador for their race.

"He is the first celebrity I know of to actually go out there and actively hunt for alien life forms. He's unusually pro-active, even putting his musical career on hold. And he is more likely to make contact because of where he is spiritually – he takes it to the max."

Luckman believes it is only a matter of time before Robbie is beamed into space, but insists the 'Angels' singer needs to consult scientists to prepare for any close encounters of the third kind.

He said: "This is an unprecedented situation, there's no guidebook. The aliens could be 1,000 times more intelligent, perhaps 100,000 times more intelligent than humans. Robbie is likely to experience enormous culture shock when he comes face-to-face with creatures from another world. He needs to know how to deal with it."

Robbie – who has become a virtual recluse in recent months as his obsession with aliens has increased – has previously said he may give up music to become a full time ufologist and claims he has had three alien encounters.

He says the first was when he saw a "square thing" pass 300 feet above his head while he relaxed on a sun lounger at the Beverley Hills hotel in California. The second was while he was playing a song he wrote about alien contact called 'Arizona'.

Robbie also says while he was in a recording studio a "big strip of black light" miraculously appeared in the room.

So these aliens, they might be 100,000 times more intelligent than humans, but they're going to choose a goofy, shirtless British pop singer to address Earth on their behalf? They don't want to pick, say, Steven Hawking or Bill Gates or Oprah or someone? Robbie would probably be more entertaining during those long nights on the spaceship, so that's something.

Robbie Williams was left terrified after his neighbour Joe Pesci threatened him with a golf club during a furious bust-up.

The 64-year-old actor saw red when Robbie invited his friends over to his Los Angeles home for a game of soccer and they blocked Pesci's driveway with their cars.

Pesci stormed out brandishing a club, ranting: "Which one of you motherf***ers blocked my drive?

"If you don't move in 30 seconds, I'm going to smash your windscreen."

Robbie – who has a soccer pitch at his home and holds weekly matches – initially thought his Oscar-winning neighbour was joking, but quickly realised the star was serious and ordered his friends to move their vehicles.

A pal of the 'Rudebox' singer compared the row to a scene from 'Goodfellas', in which Pesci played psychotic gangster Tommy DeVito.

The friend told Britain's Daily Mirror newspaper: "It was pretty terrifying in 'Goodfellas' when Pesci's character flew off the handle. Imagine seeing it in real life. Robbie has never had any sort of dispute with his neighbours before and has now given his friends strict instructions to steer clear of Pesci's driveway.

"One of the things he really likes about Los Angeles is the anonymity -big showdowns are the last thing he wants."

We had to read through that story twice before we realized that it was talking about Robbie Williams, not Robin Williams. But that was just our subconscious, which has been anticipating a Joe Pesci/Robin Williams showdown since we were subjected to a double feature of The Super and Shakes the Clown. (Hey, look at that! We didn't make a Patch Adams joke. What restraint!)
