A portion of the proceeds from Spears' bubble gum will be donated to The Giving Back Fund, the organization through which she established the Britney Spears Foundation in November (see "Britney Spears To Give Back With Performing Arts Camp"). Famous Fixins has previously teamed-up with such athletes as the Chicago Cubs' Sammy Sosa, New York Yankees' Derek Jeter, and San Antonio Spurs' Tim Duncan to offer promotional products to help benefit the personalities' respective charities of choice.
