If anyone is ever interested, tonight CBS airs its annual Grammy Nomination Concert at 10 pm, hosted by LL Cool J. and featuring performances by Train, Selena Gomez, David Grohl, Paramore singer Hayley Williams, Stevie Wonder, Justin Bieber, rapper B.o.B, country singer Miranda Lambert, Bruno Mars and Katy Perry.
The show is supposed to be a live event but not everything is live since this is a picture of Katy Perry at Nokia Plaza pre-taping a performance on Tuesday night, and probably freezing on an unusually cold LA night…
The actual Grammy Awards ceremony will air on February 13, 2011 at 8|7c on CBS.
