Last night Katy Perry performed her new single "Swish Swish," on the season finale of Saturday Night Live and brought out the internet sensation, Backpack Kid, to join her. Fifteen-year-old Russell goes by i_got_barzz on social media and is known for his famous swinging arm dance moves and his poker face stare. He's even caught the attention of Rihanna!
Of course other than being joined by Backpack Kid, in true Katy Perry fashion, she was joined by many others to put on an amazing show!
Check out Katy's (and Russell's) performance below!
