By now I'm fairly sure that the world and its mother know that That '70s Show 'cutie patooty' Mila Kunis provides the voice of Meg Griffin in Family Guy, in fact her voice has become so iconic you can probably recognize it without even looking at the screen.
However, some of the world's most infamous celebs have also leant their voices to our favorite cartoon characters, and have done so so quietly that we'd never even guess it was them! Such as these 10, for example:
1. Fergie - Sally Brown from 'Peanuts'
Known For: Her Lovely Lady Lumps
However, before Fergie gave her fergalicious self to the world, she was voicing the character of Sally in Peanuts for three '80s animated movies: It's Flashbeagle, Charlie Brown, Snoopy's Getting Married, Charlie Brown and The Charlie Brown and Snoopy Show.
2. Jaleel White - 'Sonic The Hedgehog'
Known for: Family Matters, Fake It Til You Make It, Are We There Yet?, Drunk History
While still staring in Family Matters, a 16-year-old Jaleel was also voicing the animated Sonic The Hedgehog – a role he picked up again in 1999 for the TV series Sonic Underground.
3. Vin Diesel - 'The Iron Giant'
Known For: The Fast and the Furious, xXx, Riddick, The Last Witch Hunter
Before Vince made the big time, you can hear his dulcet tones escaping from the body of a massive Iron Giant in Brad Bird’s 1999 directorial debut.

5. Jeff Goldblum - Verminous Skumm from 'Captain Planet'
