Kesha's new album was inspired by her encounters with aliens.
The 30-year-old singer features spaceships on the artwork for her comeback album 'Rainbow' and she revealed that she has seen some in real life.
Speaking on the 'Zach Sang Show', she said: "I was in Joshua Tree, totally sober, let me preface - completely f***ing 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.
"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 f***ing aliens.' They were spaceships!"
Kesha's new single 'Playing' is an emotional track, inspired by her feelings of "severe hopelessness and depression" and she revealed she has grown both as a person and an artist.
She said: "I just feel like a totally different artist - and not in a good or bad way. I had a great time. The first record was super fun, and that's where I was at. This is where I am now."
Speaking previously about her new single, Kesha said: "I have channeled my feelings of severe hopelessness and depression, I've overcome obstacles, and I have found strength in myself even when it felt out of reach. I've found what I had thought was an unobtainable place of peace. This song is about coming to feel empathy for someone else even if they hurt you or scare you. It's a song about learning to be proud of the person you are even during low moments when you feel alone. It's also about hoping everyone, even someone who hurt you, can heal."
This is Kesha's first solo single since she embarked on a court battle with producer Dr Luke in 2013, after accusing him of sexually assaulting her.
