POP superstar ROBBIE WILLIAMS claims he has seen UFOs three times. The Angels singer says he will quit singing to study aliens after his E.T. experiences.

Robbie, 34, said: "I'm stopping being a pop star. I'm going to be a full-time Ufologist." He says he also believes cult Scientology "exists" and thinks ghosts "are other worlds".
Robbie "swears" he saw the UFOs - the first when he was a kid in Britain. His second sighting was above a HOTEL in Beverly Hills. He said: "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."
Robbie says the third UFO appeared as he stood on his bedroom balcony after writing a song about alien contact. He said: "This big ball of gold light turned up. On my life."
Robbie based his 2006 Close Encounters concert tour on UFOs. After claiming he also believed in ghosts, he said: "People will think I'm mental, which I am." ***thesun.co.uk
