Ba-dum-BUM. Celebslam is reporting that Britney is showing how supportive of her man’s career she is by throwing a contest to help boost sales of his new CD. Jeannette Walls also made mention of it the other day in her Scoop column. We can’t tell yet exactly how it will operate, but the prizes have been announced:

Britney Spears is asking her fans to help sell her hubby’s album. The “Oops, I Did It Again” singer is sponsoring a contest, and the fan who helps sell the most copies of Kevin Federline’s “Playing With Fire” gets to party with Spears and K-Fed on Halloween during the CD release party. Second prize is the pair of sneakers that K-Fed wore on the Teen Choice Awards, third place gets a $200 gift certificate, and 10 lucky runners-up get a replica of a medallion that K-Fed wears almost every day.
