Katy Perry admits she’s a ‘freak’ after revealing she has an unsettling collection of celebrity hair strands.

Katy Perry said Tuesday at the iHeartRadio Prism release party in Los Angeles that she kept hair from Miley Cyrus and Taylor Swift in her purse.

“One of the first times I went to the Grammys, I got to share a dressing room with Miley Cyrus and Taylor Swift.”

“I asked them for a lock of their hair from each one of them, which is totally creepy, but awesome.”

The “Roar” singer, who was wearing a silver leotard beneath a translucent dress and big shoes, said that she “put little bows on [the locks] individually” and kept them in her handbag! She explained, “That was my little secret. I’m a freak!”

The diva also revealed Miley Cyrus is the most famous person in her phonebook during the interview and concert, which was streamed live online, and acknowledged being in love several times throughout the event, but never named current beau John Mayer by name.

The pair, on the other hand, is doing great! “Everyone knows it’s just a question of when John will propose,” an insider told Us.

Perry has been exposing a lot about herself as she promotes her new album, Prism. She recently discussed her divorce from actor Russell Brand.

“I’m not the kind of person that is always, like, ‘What doesn’t kill you makes you stronger,'” she said. “I was pretty f*****, yes. It hurt a lot. I got a good knock.”

She did say, though, that she now had a different approach to interacting with males.

“My self-worth was in someone else’s hands, which is never a good idea, because it can be taken from you at any time,” she said. “And it was, and it was shattered. But I don’t do that anymore.”
