13 Celebrities Who Believe in Aliens

The renowned British astronaut not only believes there are aliens out there, but she also thinks they could be living among us humans on earth — right now.

"Aliens exist, there's no two ways about it," Sharman told the Guardian's Observer magazine in January 2020. "There are so many billions of stars out there in the universe that there must be all sorts of different forms of life."

She also added: "It's possible they're here right now and we simply can't see them."

In the wake of a Facebook movement to storm Nevada's Area 51, presidential hopeful Sanders was asked on the Joe Rogan Experience if he'd release any information the U.S. government has about alien life forms if elected president.

"Well I tell you, my wife would demand that I let you know," he said. Assuring the host that as a senator he currently doesn't have any access to such information, if it does exist, he said that if elected president, "I'll be on the show, we'll announce it on the show. How's that?"

The beloved scientist and former host of Bill Nye the Science Guy explained his hypothesis at the premiere of Men in Black: International in New York City in June 2019.

During the premiere, Nye posted a selfie on Twitter in which he wore sunglasses to match Men in Black stars Chris Hemsworth and Tessa Thompson.

"At Men In Black premiere," he wrote. "There are 200 billion stars in our galaxy. That's likely 2 trillion planets. Aliens gotta be out there…"

During an appearance on the Zach Sang Show, the "Praying" crooner opened up about having seen spaceships in real life — and how the experience inspired her Rainbow track "Spaceships."

"I look up in the sky and there's a bunch of spaceships," she revealed. "I swear to God, there were like five to seven, and I don't know why I didn't like try to take a picture of it — I just looked at it. I was sitting on a rock, and I was like, 'What in the hell is that?' I was trying to figure it out, and then they went away. And then they came back."

"I was like, 'Those are f---ing aliens.' They were spaceships!" she recalled.

The singer is still spooked from his UFO sighting more than a decade ago, when he claimed to have seen "three flying saucers" in his L.A. backyard. "I looked at my friend and said, 'Are you seeing this or am I losing my mind?' " he recalled in an interview. As for the flashing blue lights spotted in the California sky a few years ago — later declared a missile test — he has his theories. "I'm obsessed with UFO stuff in general, so I'm all over this," Jonas said.

Much like Jonas, Kardashian does not buy the missile test "cover-up" purporting to explain the bright lights that ran across the L.A. sky in 2015. "I live for this stuff #UFO #WeAreNotAlone omg @KendallJenner this is wild!" she tweeted when the mysterious lights first hit the sky. After news outlets began guessing the source of the lights, Kardashian was skeptical: "What do we expect people to say? Obvi they are going to say it's a meteor shower. I'm such a conspiracy theorist. Let me enjoy this."

Lovato has said they know aliens are real, telling Seth Meyers, "How self-centered would we be, as humans, to believe that we are the only living things in the universe?"

"I look up into the stars and I imagine: How self-important are we to think that we are the only life-form," Perry told GQ.

Here's a good one to tell their children: When Zooey was growing up, her sister Emily told her "the Neptunians had killed my real sister and replaced her with a facsimile who looked just like her." We're pretty sure Zooey has since called her sister's bluff, but this is also assuming all of our siblings aren't from Mars.

Fox has said she believes in "everything" — including ghosts, Bigfoot and aliens. (We thought for sure she was going to say "chocolate, a new pair of shoes and Ryan Gosling, but to each her own.)

Pop quiz: "I don't believe we are the only species in existence," explained Berry, but did she say this: A) in character as astronaut Molly Woods in Extant or B) in an interview with David Letterman? (The correct answer is B, but we understand the confusion.)

According to the Wikileaks dump, the Blink-182 guitarist and singer reportedly emailed Hillary Clinton's campaign manager John Podesta in October 2016 about aliens. But his interest goes further back.

"You have to understand, I've been involved in this for a long time," he told Paper magazine. "I have sources from the government. I've had my phone tapped. I've done a lot of weird stuff in this industry — people wouldn't believe me if I told them." He even detailed a specific alien encounter.

"There is no doubt that there is life out there; the mathematics of it lead you to that absolute conclusion. In my mind, there is no doubt that the universe teems — teems! — with life in all its forms," said Shatner, whose experience playing Star Trek's Captain Kirk pretty much makes him an expert on the subject.
