Mila also voiced Meg Griffin on the short-lived FOX cartoon "Family Guy. Someone else did the voice in the beginning but I can't remember who. Seth Green did Chris Griffin's voice, and Alex Borstein from "Mad TV" provided the wife's voice.

The voice of Meg was originally provided by "Party Of Five" actress
Lacy Chabert.
Her name never appeared in the credtis, for some reason it was in her contract that her name would not be revealed.

Yeah, like being in "Party Of Five" was something to be proud of...
