Katheryn Elizabeth Hudson, better known by her stage name, Katy Perry, (born on October 25, 1984) is an American pop singer-songwriter and actress who had been one of Taylor Swift's friends. Perry had mentioned it during interviews, and they used to be seen hanging in public. They are now rumored to feuding.
In addition to being a friend of Taylor's, Perry has acheived success herself with three platnuim-selling albums, 2008's One of the Boys, 2010's Teenage Dream, and 2013's Prism. Her numorous hits include "I Kissed A Girl", "California Gurls", "Part of Me", "Wide Awake", and "Roar".
On April 15, 2010, at a Taylor Swift concert in Los Angeles, at the Staples Center, Taylor surprised her audience by having Perry rise from the stage to join her to sing “Hot N Cold”.
Perry, who was previously married to British comedian and actor Russell Brand, was in an on-off relationship with one of Taylor's ex-boyfriends, singer-songwriter John Mayer, for over a year until February 2014. They have reportedly since reunited. They even did a song together called "Who You Love" for his 2013 album, Paradise Valley. She later dated DJ/producer Thomas "Diplo" Pentz, who has worked with artists such as M.I.A. and Usher. Diplo recently tweeted a nasty comment about Taylor that caused her friend, singer Lorde, to come to her defense on Twitter.
