Pop superstar Katy Perry believes in aliens and is looking forward to asking President Obama about them.

"I believe in aliens," Perry told GQ in an interview. "I look up into the stars and I imagine: How self-important are we to think that we are the only life-form?"

Perry, who campaigned for Obama in 2012, added that she wanted to discuss the topic with the president at some point.

"I mean, if my relationship with Obama gets any better, I’m going to ask him that question," she said. "It just hasn’t been appropriate yet.”
