Otherworldly encounters: Celebrities who believe in aliens

A few days ahead of the September 30, 2021 premiere of their docuseries 'Unidentified with Demi Lovato,' the singer and actor recalled their last experience with a UFO to E! News' Daily Pop, and explained how it even convinced former "non-believer" friend Matthew Scott Montgomery and sister Dallas Lovato that aliens do exist.

"We went out into the desert in Joshua Tree and I basically saw this blue orb that was about 50 feet away, maybe less, and it was kind of like floating above the ground, just like 10 or 15 feet, and it was kind of keeping its distance from me," Lovato noted. "It was a beautiful and incredible experience." They added, "It definitely changed the way that you see the world. You have an inkling and then all of a sudden that inkling is confirmed. It changes your reality, for sure."
