Katy Perry has announced details of her new single.
The track, entitled 'Part Of Me', is taken from upcoming repackaged album Teenage Dream: The Complete Confection.
The single will be released on February 21, followed by the album on March 26.
Speaking about her updated collection, Perry said: "This is the complete story of Teenage Dream.
"It was an incredible honour to tie the King of Pop's Billboard Hot 100 record, but I'm moving forward and had a few things left to get off my chest. So this is the complete special edition of my album for my fans."
Katy Perry will perform at this weekend's Grammy Awards.
