Given that there are spaceships on the cover of Kesha's upcoming album Rainbow and one of the songs is called "Spaceship," you might assume the music will be about exploring the unknown or feeling like an outsider or some other metaphorical theme. But in reality, this motif is quite literal. An actual UFO sighting in California's Joshua Tree National Park inspired the album, Kesha said on the Zach Sang Show.

"I look up in the sky and there's a bunch of spaceships," she recalled. "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." What was even weirder was that "they came back in a different formation," she said. "I was like, 'Those are f*cking aliens.' They were spaceships!"

If you've been paying close attention, you already knew Kesha was a big believer in UFOs. "UFOs are real. I have seen them. Not playing," she wrote on Instagram in May, Billboard reports.

Kesha said on the Zach Sang Show that space will be a recurrent theme throughout her album. But it also deals with more serious topics. "Praying", its first single, is about "learning to be proud of the person you are even during low moments when you feel alone," she wrote in Lenny Letter. "I think it's healthy to talk about feeling really down sometimes ," she elaborated on Sirius XM Radio. "I think the beautiful part is that you hold onto hope ... and you keep showing up for yourself."
