Katy Perry
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. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations and she subsequently began
her music early on but it seem like she knows what style she wants to take on; and after all this is only the first of many records to come I'm sure of it."

The album has been met with generally positive reviews from critics. AllMusic praised Osment and the album, stating, ""Fight or Flight" sounds like Katy Perry with a sneer, with a sexual undercurrent that runs beneath every song and bubbles to the surface quite often."
