Sting and Bonnie Raitt are the latest artists to be added to the Super Bowl XXXVII festivities in San Diego, set for Sunday (Jan. 26) at the city's Qualcomm Stadium. Although as yet unannounced by the National Football League (NFL), a representative for Sting tells Billboard.com that the artist was personally asked by No Doubt singer Gwen Stefani to join her band for its halftime performance.

As previously reported, Shania Twain will co-headline the AT&T Wireless-sponsored halftime show.

Raitt, meanwhile, will take part in the pre-game festivities, which will also feature Santana with special guests Beyonce Knowles and Michelle Branch. As previously reported, she'll also be taking part in the Feb. 7 Salute to the Blues concert at New York's Radio City Music Hall.

The Super Bowl XXXVII pre-game show will be televised live on ABC beginning at 2 p.m. ET. Kickoff for the NFL's championship game is scheduled for 6 p.m. ET. More than 80 million people in the U.S. are expected to watch ABC's broadcast of the game.
