Katy Perry & Justin Bieber: Grammy Preview Performers
Katy Perry and Justin Bieber sure are going to have a busy next couple of months. Not only are they slated to perform at the American Music Awards, but the chart-toppers will also take the stage at the Grammy Preview Party early next month.
Wanna know who else is performing? Of course you do.
B.o.B, Bruno Mars, and country singer (and major CMA winner) Miranda Lambert are also in the performance lineup at the party, where Grammy noms will be announced. Who do you think should take home awards this year?
