Kesha has good reason to feature several spaceships on her Rainbow album cover: she apparently experienced a UFO sighting.

During an interview, Kesha said she did see what looked like “little balls of fire in the sky.”

“I was in Joshua Tree, totally sober, let me preface — completely ____ sober…I think people would be like, ‘She was on acid’ or something. I wasn’t. I was on nothing. I was a totally sober Sally, just a lady in the desert. I look up in the sky and there’s a bunch of spaceships.”

The story continued: “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. They came back in a different formation” than the one they were in previously. “I was like, ‘Those are ____ aliens.’ They were spaceships!”

And that right there was the moment Kesha decided to use spaceships for her album.

Rainbow will be out August 11th.
