Fox guest stars on the Nov. 17 episode of her husband's new TBS series, Wedding Band, and TV Guide has an exclusive clip. (The episode was presumably taped before she gave birth to son Noah Sept. 27.)
The 26-year-old plays an actress named Alexa who stars in a hit sci-fi series, Plutopia. Wearing a sexy, midriff-baring ensemble made of "genuine Italian space leather," Alexa meets Tommy (Green) after his band books a gig at Comic-Con.
"Are you on the bride's side?" Tommy asks Alexa. "The groom's?"
Astounded that she hasn't been recognized, Alexa — who also speaks Elvish! — replies, "You really don't — you don't know?
"What am I supposed to know, that pleather is readily available in Middle-Earth?" Tommy fires back.
Wedding Band airs Saturdays at 10 p.m. EST on TBS.
