London, Apr 12 : Robbie Williams is so infatuated with creatures from outer space that he is all set to broadcast a radio documentary he made on aliens and UFOs.

The documentary, 'Journey To The Other Side,' which was made by the singer in collaboration with documentary filmmaker Jon Ronson, will be broadcasted on BBC Radio.

It was earlier this year that the duo recorded the documentary near Robbie's home in Los Angeles and at a UFO conference in Nevada.

In fact, it was just last month that the former 'Take That' star confessed that he keeps scanning the sky for signs of life from other planets in his spare time and was even contemplating to buy his own observatory.

He even went to the extent of planning to chuck his pop career to become a full-time UFO chaser and insisted that aliens have visited him thrice till date.

While the first time, he was just a child when he saw a UFO, but the last two 'close encounters' had been more recent, of which he also recounted one.

"I was at the Beverly Hills Hotel and I was lying on my sun lounger outside at night, looking up. Then, about 300 foot above me, there was this square thing which just passed over my head silently and then shot off," the Mirror quoted him, as telling.
