Earlier this year, US TV airwaves were hit with a commercial for the Ninendo DSi starring R&B singer Beyonce Knowles (see below). The ad was the latest in a series showing female celebrities playing a DS, with both Nicole Kidman and Ugly Betty star America Ferrera appearing in prior DS Lite spots.

　　Apparently, though, Knowles' love of games extends beyond 30 seconds of highly paid shillery. Speaking to Billboard magazine, the former Destiny's Child member and wife of hip-hop mogul Jay-Z said she's contemplating her own workout game.

　　"I'd like to get involved in videogames since I really love Wii Fit," the singer was quoted as saying. "I think it would be a great idea to incorporate choreography because for me my workout is way more fun when it involves dancing as opposed to running on a boring treadmill. So I would love to do some kind of fitness game but incorporate dance and performance into it. I think a lot of women would enjoy that."

　　Were Knowles to collaborate on a Wii fitness game, she would not be the first celebrity to do so. Fitness guru Jillian Michaels has appeared in three games to date: Jillian Michaels' Fitness Ultimatum 2009, The Biggest Loser, and Jillian Michaels' Fitness Ultimatum 2010. In August, Daisy Fuentes Pilates featured the former MTV VJ, and next month ex-Playboy playmate Jenny McCarthy will be featured in Ubisoft's camera-based Your Shape.
