Katy Perry has revealed that she asked Miley Cyrus and Taylor Swift for a lock of their hair at the Grammy Awards.

After her performance at the iHeartRadio listening party for her new album Prism, Perry shared the anecdote with fans.

She said: “One of the first times I went to the Grammys, I got to share a dressing room with Miley Cyrus and Taylor Swift, and I asked them for a lock of hair from each of them, which is totally creepy, but awesome.

“I put little bows on them individually and put them in my purse. And that was my little secret and I’m a freak!”
