Actor Tom Cruise has admitted that he believes in aliens, saying it would be "arrogant" to think that extra-terrestrial beings did not exist.
Cruise has been promoting his forthcoming film War of the Worlds
The War of the Worlds star told a German newspaper he did not believe humans were alone in the universe.
When asked by tabloid daily Bild whether that meant he believed in aliens, Cruise said: "Yes, of course."
Cruise is an outspoken follower of Scientology, founded by science fiction writer L Ron Hubbard.
Some critics say the faith is based upon a story about alien visitors to Earth.
Cruise told the German newspaper: "Are you really so arrogant as to believe we are alone in this universe?
"Millions of stars, and we're supposed to be the only living creatures? No. There are many things out there, we just don't know."
Earlier this month, Cruise criticised actress Brooke Shields for revealing she had taken medication for post-natal depression, and later clashed with a US TV host about anti-depressants.
The American Psychiatric Association (APA) later criticised Cruise for his remarks.
War of the Worlds, based on British writer HG Wells' 1898 story of the invasion of Earth by Martians, is due to open in the UK on Friday.
