Humans have questioned the existence of life on other planets for centuries.
The “Sorry Not Sorry” singer opened up about watching the 2020 documentary Close Encounters of the Fifth Kind on the “Wild Ride! with Steve-O” podcast in April of that year. The film explores the possibility of extraterrestrial civilizations and how they can make contact with humans.
“The first encounter would be, like, seeing a UFO,” Lovato explained. “The second would be some kind of proof being left behind. The third encounter would be, like, you have some sort of interaction with the alien. The fourth is, like, you’re on board, you get abducted, and then the fifth is human-initiated contact with aliens. I sound nuts right now.” DeLonge, for his part, is a longtime believer in aliens and UFOs. The former Blink-182 frontman revealed in February 2015 that he’s read 200 books about extraterrestrials. “I don’t spend my time looking at UFO reports or talking to little green men,” he told Paper magazine at the time. “I’m way past that. If anybody tells you there’s no life in the universe, you should be turned off. That’s just such a dumb thing to say.” He added, “I don’t think we’re working underground with aliens. I don’t think it’s like that like some dumb conspiracy theorists think. I think what’s gonna happen, mark my words, is that they’re going to find the microbial life that they’ve been talking about on Mars, and then, it’s one planet over. We’re gonna send people up there, and we’re gonna find remnants of other types of life.”
DeLonge launched his company To the Stars Academy, which researches UFOs, in 2015. Two years later, the New York Times uncovered the Pentagon’s Advanced Aerospace Threat Identification Program — a secret effort funded by the U.S. government to investigate UFOs. The program ran from 2007 to 2012, but some investigators in the now-defunct division have continued their research with DeLonge’s company.

"Malibu has actually attracted a ton of UFO sightings," the reality star said during a confessional with her boyfriend. “When I was researching, I found out about this trail and this trail is supposed to have amazing alien energy. I am so excited again. Hiking, aliens — what's better?" Prince Philip According to the U.K.’s i newspaper, the late Duke of Edinburgh was fascinated by the subject of aliens. His interest seemingly spiked after his uncle, Lord Louis Mountbatten, wrote an official report about a UFO landing at his estate. “I’m quite proud of Prince Philip. Why shouldn’t he have been interested in UFOs?” writer John Hanson, who claims Philip had a dozen of his books on aliens, said. “Because for goodness sake, that is something that we should treat seriously rather than flippantly. It is a phenomenon that has baffled mankind for millennia.” Miley Cyrus The “Midnight Sky” singer detailed an encounter she had with a UFO during an interview with Interview magazine in October 2020. “The best way to describe it is a flying snowplow. It had this big plow in the front of it and was glowing yellow,” she explained. “I did see it flying, and my friend saw it, too.” Cyrus added that she saw “a being sitting in front of the flying object” and that “it looked at me and we made eye contact.” Post Malone The “Circles” rapper said in a nearly four-hour episode of “The Joe Rogan Experience” in July 2020 that he has seen UFOs in New York, Utah, and California over the years. “I’m like, ‘How did no one else see this?’ But I was there with, like, four other f--kin’ people and they saw it too,” he said. January Jones The Mad Men alum shared on Jimmy Kimmel Live! in January 2020 that she "very much" believes in aliens and even said she once spotted a UFO in a field in Iowa. “It was definitely a spaceship," Jones said of the encounter which happened when she was in her 20s. "Or a shooting star that just couldn’t figure it out.” Bill Nye The former Bill Nye the Science Guy host confirmed his belief in aliens when he tweeted from the Men in Black: International film premiere in June 2019. “At Men In the Black premiere,” he wrote. “There are 200 billion stars in our galaxy. That’s likely 2 trillion planets. Aliens gotta be out there …” Kurt Russell The Hateful Eight actor revealed on Jimmy Kimmel Live! in November 2018 that he witnessed a possible UFO sighting years ago. "I was flying and there were these banks of lights in the shape of a triangle right near the airport,” he said. "Years later, I come home and Goldie [Hawn] is watching this show on UFOs and the most reported one of all time was this one in Phoenix. I start to see this show and I say, ‘Wait a minute, that’s the night I was landing in Phoenix.’” Aaron Rodgers The Green Bay Packers quarterback claimed he spotted a UFO when he was 20 years old. "It looks like commercial jets kinda flying – or maybe it's a military jet – and they're trying to figure out what's coming through the clouds and you see like a fiery movement of cloud, I guess, coming through the sky," Rodgers said on the "You Made It Weird" podcast in March 2016. "Then the plane eventually runs into the spaceship, which is coming into orbit. It was like ... a large, orange, left-to-right moving object." Jennifer Lawrence The Passengers star shared her fear of aliens on The Late Show with Stephen Colbert in December 2015. "Based on history, when we find each other, we kill each other," Lawrence explained. "I don't feel like aliens are going to be like, 'Oh, great! Let's get along.' They might not. They might want to destroy us. Have you seen a Tom Cruise movie? So, sometimes I look up into the stars and I'm like, 'Oh, wow. Oh, God." Tom DeLonge "I don't think we're working underground with aliens. I don't think it's like that like some dumb conspiracy theorists think," the Angels & Airwaves singer told Paper magazine in February 2015. "What's going to be are remnants of other civilizations: architecture, old monuments, machinery, things that have been fossilized, whatever, and then that will get dripped out for another 30 to 40 years. Maybe there was a civilization there." Halle Berry The Catwoman star told David Letterman in July 2014 that she doesn't think humans are the only life forms in the universe. "I don't believe we are the only species in existence," Berry said. "It might take us 20 years to get to those other life forms, but I think they are out there." Jaden Smith The "Ghost" rapper confirmed his belief in aliens after an illuminating conversation with Barack Obama. "I talked to President Obama about extraterrestrials. He said he could neither confirm nor deny the existence of aliens, which means they're real," Smith told Wonderland magazine in April 2013. "If people think we're the only people that live in this universe, then something is wrong with them." Russell Crowe In March 2013, the Gladiator star recorded two glowing red and yellow objects moving in the sky in Sydney. Crowe uploaded the video to YouTube claiming that he captured a UFO sighting. Demi Lovato The "Anyone" singer said she believes in aliens in a June 2014 interview with Seth Meyers. Lovato added that she also thinks mermaids could be real. "I believe that there could possibly be mermaids, which is actually an alien species that lives in parts of the Indian Ocean, which we have never explored before," she said. Dwayne 'The Rock' Johnson "I believe that we're not the only ones; it'd be arrogant to think that," the Jumanji: Welcome to the Jungle star said in an interview with Vice in June 2016.

Katy Perry "I believe in aliens," the "E.T." singer told GQ in January 2014. "I look up into the stars and I imagine How self-important are we to think that we are the only life form." Tom Cruise The Mission: Impossible star said he doesn't think "you can actually count it out" that there's life on other planets. “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,” he told The Sun in April 2013. Alicia Keys The Grammy winner is not only convinced that aliens exist but thinks everyone has experienced an encounter with them. "I'm sure you've seen a UFO," she told BuzzFeed in October 2013. "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?" Keanu Reeves "I think it more likely than not. The cosmos is a pretty big place," the Matrix star said in an interview with Boston.com in December 2008. Gigi Hadid and Zayn Malik The model confirmed that both she and the former One Direction member believe in other life forms beyond the stars. "My boyfriend's really into aliens," she told Harper's Bazaar in May 2017. One year earlier, Malik told Glamour that he decided to leave the boy band after an alien contacted him. "An alien spoke to me in a dream," he said in July 2016.
