Pop star Katy Perry, who performed at the Super Bowl along with other artistes including Beyonce Knowles, calls herself a huge fan of the singer.

"Oh my God. I'm such a Beyonce fan," she told Elle in the magazine's March issue.

"I was like, Finallllly. Finally I see you. I don't see some propaganda version of you. I see you. I relate to who you are,` added the 30-year-old Perry.

Perry also cleared the rumours doing the rounds about her friendship with Taylor Swift, calling her the `sweetheart`, reports people.com.

"You've got to name someone the villain, someone the princess, someone the mom, the dad type -- you know there always have to be characters," she said.

"As pop figures, we're all characters. And the media uses that. Who is the sweetheart, who is the villain? You know. Taylor's the sweetheart. Kanye's the villain. That's the narrative,` added Perry.
