The black-and-white themed party took place at Pacific Park Amusement Park. Guests included Cody's little sister Alli Simpson, her BFF Madison Pettis, Jessica Jarrell, Debby Ryan, Shake It Up's Bella Thorne, Jasmine V, Modern Family's Rico Rodriguez, and Aaron Fresh. Nick Cannon was the star DJ for the bash (check out the above TwitPic of Cody DJing with Nick!), and Jessica sang a special Happy Birthday dedication just for Cody.

To keep in tradition with his Australian roots, Cody and his guests noshed on Australian barbecue, hamburgers, and salads, and he had a huge chocolate cupcake tier birthday cake from Crumbs Bakery. But what was Cody most excited for? The rollercoaster, natch!

"I just want to thank everyone for being here tonight," Cody said at his party. "2011's going to be a great year for all of us!"

Does Cody's party sound like it was fun? What kind of birthday cake would you want to have at your party?
