Keeping up with her Prism promotion, KP headed over across the pond to perform her biggest single to date, “Roar” on the X-Factor UK stage. Making sure to dress the part, Katy was decked out in tiger gear as she stood and belted out the lyrics to the roaring crowd. Is it just us or does this song never get old?

And to wrap up Day One of Katy Perry Week, the super star took getting the word out about Prism into her own hands by delivering it to Wal-Mart stores herself! Okay, it may just be for this new commercial but still – how crazy would that be if you saw her stocking shelves with Prism?
