Los Angeles, Jul 9 (IANS): Singer Kesha says her comeback album "Rainbow" was inspired by her encounters with aliens.

The 30-year-old's album's cover art features spaceships and she says she has seen aliens in real life, reports femalefirst.co.uk.

"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," Kesha said on a TV show.

"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," she added.
