Katy Perry's creations will make their debut in March (12) with the release of the Collector's Edition for The Sims 3 Showtime.
She tells The Hollywood Reporter, "I love how you're able to play out different stories through your Sims characters - giving them different careers and watching them succeed.
"It's cool to see the Sims' stage performances in The Sims 3 Showtime decked out just like my California Dreams Tour - even my cotton candy video screens are in there! I always like to think of myself as a cartoon, and now I'm a Sim!"
The singer will also be featured in the brand's upcoming advertising campaign.
