The R&B star Usher and former Guns 'N Roses guitarist Slash are supposed to join the Black Eyed Peas, who are the main halftime act for the NFL championship game between the Pittsburgh Steelers and Green Bay Packers in Dallas.

Following the game, Usher will play host at the "Official Super Bowl XLV Post Game Afterparty" Sunday at BlackFinn Saloon in Addison, Tx. He is also expected to be the guest performer at Mark Cuban's invitation-only DirectTV/HDNet Super Bowl Bash Saturday.

The sheer star power headed to Dallas for Super Bowl week should help thaw some of the ice that has blanketed the area.

Ashton Kutcher and Demi Moore are expected. Garth Brooks is slated to participate in a football camp for kids. Pamela Anderson is hosting a party with Playboy models. Prince, Snoop Dogg, Flo Rida, Duran Duran and Kid Rock are among those performing at events leading up to the big game. Diddy is having a big bash. Bon Jovi's Richie Sambora is having a fashion show featuring the Dallas Cowboys cheerleaders.
