BEIJING, April 26 -- Mariah Carey has teamed up with Pepsi to write and produce 20 original voice and music ringtones for release this summer.

    The ¡°We Belong Together¡± singer will also star in a national commercial promoting the Pepsi Cool Tones & Motorola Phones partnership as part of her deal.

    ¡°I had a lot of fun with this project,¡± the Grammy winner said in a statement. ¡°It was a great creative outlet because musically I could do things here that I would never think to do for one of my albums.¡±

    As part of the deal, Carey will also kick off her summer tour, for which dates have yet to be announced. The performance will mark the ¡°Butterfly¡± singer's first full-scale concert in more than three years.

    The Pepsi Cool Tones promotion will eventually feature upward of 100 original ringtones from several artists, with Carey the first to sign on. Her contributions will be written exclusively for the promotion.
