We were shocked to lean that Fergie, who became famous with the Black Eyed Peas, got her first taste of Hollywood voicing Sally from Peanuts. A true child of the '80s, the pop star voiced the iconic character in three Charlie Brown specials.

Fergie was nine-years-old when she first voiced Sally in It's Flashbeagle, Charlie Brown. One year later she returned for Snoopy's Getting Married, Charlie Brown and The Charlie Brown and Snoopy Show. That was 1984. In 2003, she joined the Black Eyes Peas for the album Elephunk.
