Wow, we couldn't think of any two people less alike than Mila Kunis and Meg Griffin. Meg Griffin is consistently poked fun at throughout the entire Family Guy series. Whether it's because of her weight, hair, glasses, or nerdiness, she is always being made fun of in some way. In short, she is presented as an unattractive loser, and Mila Kunis is anything but that.
Meg was originally voiced by actress Lacey Chabert, but Mila Kunis ended up winning over Seth Macfarlane with her audition. He has even been quoted as saying how great it was to have a teenager (which Kunis was at the time) playing the role. Now that you know it's Kunis behind the voice of Meg Griffin, we bet you won't stop thinking about it next time you see an episode.
