Beyonce and Nintendo team up for digital fashion line

Singer and actress Beyonce' Knowles and her mother, designer Tina Knowles, have teamed up with Nintendo. The pair will provide designs for the fashion-themed "Style Saavy" game for the Nintendo DS and DSi.

Players can incorporate the designs on their digital creations in the game.

Nintendo and Beyonce started their relationship last year with an ad campaign for "Rhythm Heaven," a music-themed game for DS and DSi. The video game company has a series of new ads around the pair's latest venture that will air on Nickelodeon.
