Which singer's real name is Katheryn Elizabeth Hudson?
Katheryn Elizabeth Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and television judge. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson under her birth name in 2001, which was commercially unsuccessful.
Perry rose to fame in 2008 with her second album, "One of the Boys", a pop rock record containing the singles "I Kissed a Girl" and "Hot n Cold". The former track also sparked controversy for its themes of lesbianism. Her third album, "Teenage Dream" (2010), ventured into disco, and was her first record to top the U.S. Billboard 200.
