Robbie Williams camping out to spot UFO

Robbie Williams has started camping in a bid to spot a UFO.

The ‘Angels’ singer – who is fascinated with aliens – has purchased a tent, sleeping bag, cooking gear and survival equipment so he can sleep under the Californian stars in the hope of seeing an extraterrestrial spacecraft.

A source close to the star – who lives in Los Angeles - told Britain’s The Sun newspaper: “Robbie has been taking pals out to the woods for long weekends. He wants to live like a cowboy in a Western. He also has a fascination with UFOs and thinks he has more chance of seeing one away from Los Angeles’ bright lights.”

Earlier this year, it was claimed Robbie was planning to splash out £2.5 million on an alien observatory after spending all his free time visiting Arizona's National Optical Astronomy Observatory, in Tucson.

A source said: "He is leading a bizarre existence at the moment, vanishing into the desert to look at starts in far-flung galaxies. He is dead set on buying himself an observatory in the desert, which can cost up to £2.5 million. He is hooked on all things from outer space."

Robbie - whose 2006 'Close Encounters World Tour' was alien-themed – has previously claimed he has been visited by spaceships on three occasions.

Describing one close encounter of the third kind, he said: "I was lying on my sun lounger outside at night. Above me was a square thing that passed over my head slightly and shot off."
