Katy Perry and Ubisoft are besties

"Including Just Dance 2 in my Last Friday Night music video was so rad," said Perry. "Kathy Beth Terry and I are big fans of the game!"

Showing the worlds of gaming and music, and Perry in particular, are getting closer all the time, Ubisoft is also sponsoring Perry's North American California Dreams tour and are including her hit song Firework in the Just Dance 2 game.

For their part, Ubisoft seem stoked with the arrangement. "Katy Perry music videos become instant pop culture events worldwide and for our game to be included is an honour and testament to the popularity and appeal of the Just Dance franchise," said Geoffroy Sardin, Ubisoft senior vice president of sales and marketing.
