"Aliens!" Lovato, 23, exclaimed when a reporter from the magazine asked her what she believes in. "I've seen a UFO."
The pop star claimed she had the sighting "a couple of years ago."
"I was walking outside and I looked up and it almost was like there was a worm in the sky," she explained. "It was changing shapes and moving all over the place."
Surprisingly, this isn't the first time Lovato has discussed aliens in an interview. In June 2014, the former Disney star was a guest on Late Night With Seth Meyers, where she spent a good portion of the show backing up the conspiracy that mermaids are actually aliens. (Apparently, she got the idea after watching an "extremely convincing documentary" on the Discovery Channel.)
"I know that [aliens are] real," she said at the time. "How self-centered would we be as humans to believe that we are the only living things in the universe?"
"You know Atlantis, how there was that underground city? 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 continued. "And Christopher Columbus has actually seen three mermaids on his way to America."
When Meyers asked if she thinks real mermaids look like the ones depicted in books, she was quick to respond, saying, "No, I mean they're aliens!"
