Katy Perry brought her 'Roar' music video to life over the weekend for a show-stopping performance on Saturday Night Live.

Katy opted for a leopard print top and hot pants for her 'Roar' performance, singing on a jungle-themed stage and backed by dancers to the set, before changing to play her next 'Prism' song for the first time on television.
