The 'I Kissed A Girl' singer has finished her rehearsals for this weekend's ceremony.
Katy Perry has revealed that she is looking forward to performing live at this Sunday's (12th February) Grammy Awards 2012.
The 'Last Friday Night (T.G.I.F)' star will be making her first appearance on stage for a TV broadcast in the country since news broke of her marriage breakdown to comedian Russell Brand.
Taking to her Twitter account earlier today (9th January), the star tweeted: "Just finished rehearsals for Grammy's... I'm. so. excited. #somethingscooking."
She will join the likes of Rihanna, Chris Brown and Adele – who is making her live return since undergoing throat surgery last year.
Meanwhile, Katy could be set to take one of the vacant judge's seats on The X Factor USA after Simon Cowell recently revealed that it would be "fun" to work with the star.
