Katy Perry’s obsession with cats was never a secret, but for the first time this week, we learned about her hidden collection: celebrity hair.

Her third studio album, Prism, dropped Tuesday, and in the midst of her own personal press whirlwind, she performed at her iHeartRadio listening party and, after performing, she took questions from some of the fans in the audience.

And this is where things get interesting.

After a fan asked her what she keeps in her purse, Katy shared an interesting anecdote about her early days at The Grammys.

“One of the first times I went to the Grammys, I got to share a dressing room with Miley Cyrus and Taylor Swift,” Katy said, according to E! Online.  “I asked them for a lock of their hair from each one of them, which is totally creepy, but awesome.”

What’s even more surprising? They both said yes.

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

As long as Katy doesn’t use Miley’s hair to create a swarm of twerking clones, we’re good.
