Katy Perry has excited her fans by announcing a comeback performance at the Grammys and drastically changing her look.
Typically brunette, the star has dyed her hair blonde and gone for a pastel pink look, according to her Twitter profile picture.
The pop singer, who hasn't released an album since 2013, and the only offering since then has been her single Rise, which had a lukewarm reception by fans used to her previously steady stream of earworms.
Her work since then has mainly taken place off-stage, she's been on tour and spent the bulk of last year campaigning for Hillary Clinton.
