Katy Perry has revealed some odd details about her life, including that she collects celebrity hair and believes in aliens.
The Roar singer told fans in a Q and A session about keeping locks of other singers' hair, according to The Sun.
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). I asked for a lock of their hair.
"I put bows on them and put them in my purse. I'm a freak."
Katy also told Us Weekly 25 unusual facts about herself, which included the revelations that she has a ticket to outer space and she believes in aliens.
Meanwhile, when she was shooting the video for her single Unconditional in East London recently, Katy missed her cat Kitty Purry so much that crew went out and found a kitten for her to play with that was brought to the set.
The kitten wasn't taken back home with her, but a spokesperson said she had called it Prism after her new album.
