American popstar Beyonce has begun her promotions for the famous Super Bowl half-time show this Sunday.

While the event centres around the clash between the San Francisco 49ers and Baltimore Ravens, the half-time show takes plenty of the headlines.

This year, Beyonce will take to the stage and she is preparing by posing in a promo shot dressed as a referee for this weekend's highly-anticipated contest in New Orleans.

Reports have claimed that Beyonce will be joined by her Destiny's Child bandmates during the performance.
