Katy Perry wants to be friends with Daniel Radcliffe

London: Pop star Katy Perry wants to be friends with actor Daniel Radcliffe, who reportedly has a huge crush on the singer.

The 28-year-old singer, who is currently dating singer John Mayer, urged the "Harry Potter" star to call her so that they can be friends and hang-out together, reported Contactmusic.

"Oh please, this isn't the third grade. Just ring me, Daniel. Don't be shy, or get your people to call mine if you like," Perry said.

"I am totally taken so it's not about that. I think he's cool and I'd really like to get to know him. We'll all go out and party," she added.

Last year, Radcliffe said that he had a "massive crush" on the 'Roar' hitmaker.
