Last month, Family Guy returned to our screens for a remarkable 12th series. Very few would ever have thought the 20th Century Fox show would reach such a landmark. Cancelled in 2003 and put on a two year hiatus, many thought they had seen the last of Peter Griffin and co. However, following its revival in 2005, the adult animation has gone from strength to strength, spawning a spoof film trilogy and even a video game. Family Guy and its cast have also been nominated for thirteen Emmy Awards, with four wins, proving that the show and its characters warranted the renewal. Mostly following Peter, his anthropomorphic pet dog Brian and dysfunctional family Lois, Stewie, Meg and Chris, Family Guy has also featured some top drawer celebrity guest stars down the years. Some of the television, film and music industry's most famous stars have appeared on the show in one way or other, either playing themselves or merely lending their vocal chords to a fictional character. Some of the appearances have been subtle, while there will be some famous people on this list that fans will instantly remember. And here, without further ado, we take a look at the show's 10 Best Guest Stars Ever. Click "Next" to get started.
