Pick the Best Britney Spears Commercial

Would you rather see Britney Spears as a surfer gal, a hippie chick or dressed in androgynous 1980s clothes?

Instead of just sitting idly by their TVs, Superbowl fans are getting a chance to cast Britney Spears in the commercial role of their choosing by voting in an online ballot.

Spears -- whose Super Bowl commercial last year was a hit -- will be back again this year in a 90-second blockbuster that will debut during the first quarter of the Sunday's game. The spot, called Now and Then , will be a montage of Pepsi ads through the decades from the 1950s and '60s, right up through 2002.

Pepsi joined forces with Yahoo! to let people surfing the Web choose which particular Spears spot they would like to see again during Sunday's big game. If you want to vote, to look at behind-the-scenes video of Spears across the ages and choose your favorite.

The winning commercial will be made into a 30-second commercial that airs in the second quarter of the game. Voting ends 11:59 p.m. Eastern time on Friday, Feb. 1.
