Katy Perry has announced that she will be taking her new husband Russel Brand's surname.

The singer is in the process of changing her last name after the pair got married in India last month.

"Like if I'm at an event or something like that and they want special attention. They go, 'Mrs. Brand!' and I go swoosh,'' Perry told Ellen Degeneres.
