50 Cent believes aliens exist.
The 'Candy Shop' rapper is a massive fan of fantasy novels and is certain there are other life forms which are deliberately kept hidden from the public.
He said: "I read a lot of science fiction because I just want to get away from what's going on at the time, I read fantasy books.
"Like things about different planets and other worlds. It's interesting how often they've made films with aliens in them and it has to come from somewhere.
"Why do I keep seeing the aliens landing on earth in films? I believe something is going on that they ain't telling us!"
The 34-year-old rapper has never made contact with aliens or UFOs himself, and is worried his fans will think he is crazy when they find out he is obsessed with extra-terrestrials.
He added to BANG Showbiz: "I've never seen a UFO. I'm crazy enough to be putting what I've said out there. People will be seeing this about UFOs and stuff and thinking '50 getting high!' "
50 stars in British gangster film 'Dead Man Running' - in UK cinemas now - and is releasing his latest album 'Before I Self Destruct' next month.
