Robbie Williams’ obsession with aliens recently got him dumped by his girlfriend, and a New York “expert” on extraterrestrials thinks Williams may soon find himself orbiting the earth in a spaceship.

Michael Luckman, director of the New York Centre For Extraterrestrial Research, says Williams’ obsession means he’ll soon be abducted by aliens and he should prepare himself for it.

“Robbie is now becoming a point man for contact with extraterrestrials,” Luckman told BANG Showbiz. “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.”

Williams’ girlfriend, Ayda Field, who’s starred on television shows Will & Grace and Days Of Our Lives, allegedly dumped him after he became so obsessed with aliens that he almost ceased spending time with her. He has reportedly spent more time in front of a computer researching aliens on the internet than he has around people, which led Fried, who he’d been seeing on and off for more than a year, to give him the boot.

“Robbie has become more obsessed than ever with aliens,” a source told the U.K.’s Daily Star tabloid. “Some nights he would not go to bed.”

Now that Williams has more free time with his friends in spaceships than he did before, Luckman says this makes him a prime candidate for abduction and he should be ready for what he’ll face.

“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 WILLIAMS’ obsession with extra-terrestrials has just jumped to lightspeed.

The beardy pop nob has been spending his free time – which is about 18 hours, seven days a week – visiting observatories in the Arizona desert.

Rob has been peering through telescopes looking into space for signs of life on other planets.

Telescopes … Robbie’s got his eye on one

Surely writing a new album is more important than staring at the heavens like eccentric, xylophone-playing Sky At Night TV host PATRICK MOORE?

Robbie has been visiting the National Optical Astronomy Observatories in Tucson, Arizona, pictured above, to do his star gazing.

He has become so obsessed with his new hobby he is planning to buy an observatory – a mere snip at £2.5million.

More money than sense, eh?

A source said: “Some of Robbie’s acquaintances in LA have been having a chuckle at his expense.

“He is leading a bizarre existence at the moment – vanishing into the desert to look at stars in far-flung galaxies. He is dead set on buying himself his own observatory in the desert. He is hooked on all things from outer space.”

I always thought Robbie was wired to the moon. The singer based his 2006 Close Encounters concert tour on UFOs.

And in the last few months he has got friendly with crackpot ex-sports presenter DAVID ICKE, who believes key world leaders, including GEORGE W BUSH and TONY BLAIR are reptilian aliens disguised as humans.

Robbie also appeared on radio last week to talk about three dramatic sightings he has had of UFOs in LA – and his desire to hang up his mic to study aliens after his ET experiences.

Robbie said: “I’m stopping being a pop star. I’m going to be a ufologist.”

He says he also believes the cult of Scientology “exists” and thinks ghosts “are other worlds”.

He added: “I was lying on my sun lounger outside at night. Above me was a square thing that passed over my head silently and shot off.”
