BRITNEY’S COKE DEAL!

The star's half-time Pepsi promotion is costing the soft drinks giant millions...

Britney Spears is set to star in two of the most expensive television adverts ever made during breaks in this Sunday’s (February 3) American football SUPERBOWL.

Pepsi are paying $8million (£5.6million) to have their product promoted by the princess of pop during the breaks in the match. Traditionally, these are the most expensive on American television and can command a network audience of 80 million.

The first ad, running at 90 seconds, will take place during the first quarter interval. It will show Britney Spears, dressed in the fashions of the past 50 years, singing the jingles of Pepsi from the 50s through the decades to the present. It starts in black and white and moves to colour.

The second ad, a 30 second clip to run during the half-time break, will be chosen by Britney Spears fans. They can view a selection of alternatives on the Pepsi site and then vote for their favourite.

US advertising experts and economic watchers feel the huge cost is worth it for the drinks giant.

“The Superbowl is a unique viewing experience. Consumers really do expect entertainment from the commercials,” Michael Wolf told USA Today. He added that the glitz and pricey showbiz factor is something viewers are keen to see to lift the spirits after September 11 and the difficult months that followed. “They want to be back to normal and feel like they are going to get the usual kind of Superbowl experience.”

Britney Spears will be the only star helping lift fans. Paul McCartney, Mary J Blige and Mariah Carey will perform during a pre-match show, while U2 have agreed to perform at half-time.

St Louis Rams and the New England Patriots will battle it out for Superbowl XXXVI at the Louisiana Superdome.
