KATHY GRIFFIN(@kathygriffin) AND NATHAN FILLION(@nathanfillion) CAMEOS FOR THIS SUNDAY’S ALL NEW ‘AMERICAN DAD'(@AmericanDadFox) THIS SUNDAY NIGHT ON FOX(@FOXBROADCASTING)!

Imagine if your liver talked to you…then imagine if your liver talked to you and it was Richard Castle aka Nathan Fillion. Welp, apparently the producers of American Dad thought the same thing and as such they have Castle’s Nathan Fillion set to play someone’s Liver. This is fresh off us finding out a few weeks ago that he will also be doing voice-over work for an upcoming episode of Robot Chicken!

Also, Kathy Griffin is set to cameo as a character named “Kelly”. Not sure what her deal is, but tomorrow we will have the previews up and we can find out. American Dad is all new this Sunday night on FOX check your local listings!
