NEW YORK: 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).
