Kim Kardashian hard at work on 'American Dad' set
Kardashian posted the above picture of herself (looking cute in a dark gray jumpsuit) with the caption: "Guess what guys!!!! I'm going to be on American Dad! You have to tune in to see what my character is!"
Being a new mom, she must have missed the previous announcement about the role -- she's reportedly playing a furry alien who falls for Roger after her ship crash-lands.
Kardashian will join a list of Season 10 guest stars that includes Cloris Leachman, Ellie Kemper, Alison Brie, Jane Krakowski, John Cho, Olivia Wilde, Zooey Deschanel, Terry Crews and Stanley Tucci.
"American Dad" airs Sunday nights at 9:30 p.m. ET/PT on FOX.
