Katy Perry has debuted new track ‘Part of Me’ at the Grammy Awards, and the lyrics have prompted questions as to whether it’s about her ex-husband Russell Brand.
The pair split late last year, but lines such as ‘look at me/ I'm sparkling/ You will never put me out again/ So you can keep the diamond ring/ It don't mean nothing anyway’ did not leave much to the imagination.
‘Part of Me’ is released on February 21.
Perry also sang hit single ‘ET’.
