Katy Perry Isn't The Only Celebrity Who Believes In Aliens: 5 More UFO-Obsessed Celebs

Katy Perry appeared as the cover girl for the February issue of GQ magazine, where amongst other things, she revealed that she genuinely believes in extraterrestrial beings and that we are not alone. She also spoke about praying for large breasts, regretting that prayer in later life, her dislike of cannabis, losing her virginity, the beginnings of her career and much more, but it was her other worldly beliefs that has caught on.

Katy believes that we are not alone

"I believe in a lot of astrology. I believe in aliens. I look up into the stars and I imagine: How self-important are we to think that we are the only life-form?" she questioned. "I mean, if my relationship with Obama gets any better, I'm going to ask him that question. It just hasn't been appropriate yet."

Whilst we're sure Obama can't wait for the next time he see's Perry and gets to talk about aliens, it might not be the first time that the most powerful man on earth has been questioned on the subject by a famous face, after all, Perry is not alone in thinking that we are not alone.

Some famous faces who look to the stars and think that we are not alone probably won't surprise you, but others who believe in UFOs and aliens may strike you as a surprise. We've rounded up 5 more stars who believe that the truth is out there.

Cruise is certain that we are not alone

This one probably wont come as too much of a surprise, but Tom Cruise is a stern believer in the idea that we are not alone. The Scientology poster boy obviously holds the beliefs of his religion close, including the parts about aliens and UFOs, and has spoken publicly about said beliefs at various points in the past.

Most recently, the actor revealed some of his ideas in press conference for the film Oblivion, when he said, “I don’t think you can actually count it out. It might be a little arrogant to think we were the only ones in all the galaxies throughout the universe — but I’ve never met one!”

Elvis Presley was told that aliens visited earth when he was born

Elvis Presley was also a believer in the thought that we are not alone, stating in his time that we are most likely not alone in the universe, with biographers and confidants revealing more after his death. The King even claimed that there were sightings of "a strange, unidentified blue light" above his Tupelo, Mississippi home on the night he was born - according to author and Elvis biographer Michael Luckman.

There are various other reports that link Elvis to aliens, including the known-story that when he was a child, Elvis believed that he was visited by an extra-terrestrial visitor who showed him visions of his future. Although he was never very publicly open about his apparent beliefs, Elvis' friend and hairdresser Larry Geller has since said that the King developed something of an obsession with paranormal and spiritual activity and was always open to the idea of alien life.

Fox thanks History for opening her up to new ideas on aliens

During an appearance on The Ellen DeGeneres Show in 2012, the Transformers star gave her argument as to why we are not alone in the universe, saying that TV series such as History's Ancient Aliens have helped open her eyes to what's out there.

"Everyone thinks I'm crazy," Fox said during her interview. "It's all about the theory that these megalithic structures were possibly built by—not necessarily like little green aliens, but maybe future humans that they call ancient astronauts—that did some sort of time travel. Something extraterrestrial was involved."

Alicia Keys thinks that aliens walk among us

Whilst most people may agree that we probably aren't alone in the vast expanse of the universe, Alicia Keys thinks that contact has been made and aliens are living amongst us at this very moment. Her Men in Black-like beliefs were revealed in a 2013 interview with Buzzfeed.

Answering "yes" to whether she believed in aliens and whether they walk among us, the multi-Grammy winning singer and songwriter went on to say that she has actually been in contact with Earth-based aliens, saying "I’ve met some serious aliens in my life, for sure [laughs]. I’m sure you’ve seen a UFO. Haven’t all of us seen something flying in the sky, and it’s at some random time of night that doesn’t make sense, and it’s not the shape of a plane?"

Maclaine regularly speaks on UFOs and aliens life

One person who has been discussing the existence of extraterrestrial visitors and UFOs longer than most of the people on this list have been born is Shirley MacLaine, one of Hollywood's most dedicated UFO investigators and believer. Shirley says that UFO sightings are a regular occurrence at her New Mexico ranch, although she does admit to never coming in contact with an alien in person.

"I've seen a mothership here, and I've seen them at my ranch," she told Oprah during an interview at the beginning of the decade. "One famous day, a friend of mine was sitting in my hot tub out there, and three UFOs came over and hovered over the hot tub for about 10 minutes."

The firm believer went on to say that alien activity is so commonplace in New Mexico because the universe-wanderers are attracted to the strong presence of crystals in the area. She explained, "Crystals amplify the consciousness. They're attracted to that crystal amplification."
