The Sims 3 Showtime: Katy Perry was just not enough Katy Perry-themed expansion content for The Sims 3. An absolutely unacceptable dearth of Katy Perry remained.
Luckily, EA has rescued us from a life of insufficient simulated Katy Perry paraphernalia with the announcement of The Sims 3 Katy Perry's Sweet Treats, which lets you decorate your Sims' homes in the style of an imaginary "Candyfornia, complete with cupcake-themed guitars, candy playground equipment and delicious cotton candy trees."
You'll be able to cover your Sims and their homes in virtual candy this June on PC and Mac. It's a good thing The Sims 3 doesn't connect to SimAnt.
