Katy Perry might not seem like the sentimental type but she definitely is. In fact, Perry has a bit of memento from her BFF's Miley Cyrus and Taylor Swift. It's not as hair-raising as it sounds but it does involve a bit of hair.

During Katy's first appearance at the Grammy Awards, the "Roar" singer turned into quite the fan girl when she met Miley Cyrus and Taylor Swift. Rather than keep a photo from the meet, Katy had other gifts from the girls.

"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 their hair from each one of them, which is totally creepy, but awesome," shared Perry in an interview with the Mirror.

The creepiness doesn't stop there because Katy claims she brings the locks of hair with her - everywhere she goes.

"I put little bows on them individually and put them in my purse," stated Perry, adding, "And that was my little secret and I'm a freak."

"Freak" may be a little overboard. Perry's confession certainly proves she's a fan girl of the "Wrecking Ball" and "Red" singer. As for Perry's own musical ventures, the singer recently released her latest album "Prism" which according to Entertainment Weekly's critic, Nick Catucci, is filled with "bouncy, joyous tunes." However, not all songs on the album were all happy and perky tunes because one song was obviously a break-up song inspired by Perry's divorce with Russell Brand.

"Well, imagine what you go through," says Katy to EW, adding, "Imagine what happens when you go through a break up. We all go through break ups and we all get very depressed and desperate. The lyrics are very exact and autobiographical. That's how I write. But the one thing about those lyrics is you can hear me finding my strength throughout the song. It starts off really low and then I kind of stand up for myself and say, 'No!'"

"All the other songs are stories from different times in my life. It's people making assumptions. It's kind of hard because I am so vulnerable and I am [such an] open book, but I don't feel like I want to hand over a specific story about each and every song. I don't feel like I want every song to come with a little package, a little tabloid-al package because it's like, 'Why don't you let the song be a little unspecific to the listener? Then the listener can use it and relate to it in their own way. So, not every song comes up with an excerpt. They're biographical but all you're going to get in the songs is just that," continues Perry.
