Demi Lovato visited Late Night With Seth Meyers last night to talk about all sorts of serious stuff like mermaids, aliens, Bigfoot and the Loch Ness monster.

Though she doesn’t believe in the last two, the "Neon Lights" singer chatted about her belief in mermaids and aliens with Seth Meyers, telling him "I know that they are real!"

Demi, who debuted her new ombre fade, said she saw an “extremely convincing documentary” on the Discovery Channel—and no, she’s not talking about "The Little Mermaid," though Seth totally had to ask.

“How self-centered would we be, as humans, to believe that we are the only living things in the universe?” she said.

Check out her interview below, then let us know if you think Demi is totally serious or just joking around with Seth? Do YOU believe in mermaids? Sound off in the comments!
