Beyonce will be joined onstage by fans at the upcoming Super Bowl in the US.

The Grammy-winning diva is set to perform at the American football championship - at the Mercedes-Benz Superdome in New Orleans - on February 3.

Pepsi, sponsor of the half-time show, has now announced that 100 of the chart star's fans will hit the stage with her.

A contest that kicks off on Saturday will allow fans to submit photos of themselves in various poses, including head bopping, feet tapping and hip shaking.

Those pictures will be used in a TV ad introducing Beyonce's half-time performance, and 50 of those people - along with a friend - will be selected to join the Love On Top singer onstage.
