London, Mar 10: British pop singer Robbie Williams is planning to quit his singing career to become an ufologist, or alien investigator.
The Angels star revealed this while being interviewed by soul singer Joss Stone for a British radio show, contactmusic.com reports.
He said: "Seriously, I want to go out and investigate these things. I'm stopping being a pop star and becoming a full-time ufologist.
"We could be like Mulder and Scully (The X Files FBI agents) in real life. You're always mega-busy but I've got nothing on at the minute."
Williams also claims aliens have visited him on at least three occasions, and witnessed a "big strip of black light" during recording in a studio in Los Angeles.
However, the 34-year-old insists he can understand if the public views his latest obsession with concern.
He added: "People will think, 'This geezer's been in rehab, he's off his head.' How mental are they going to make me out in the papers."
