Ground Floor Ground Floor

It's a Pitch Perfect reunion for Ground Floor's Skylar Astin when his costar from last year's hit movie — and real-life girlfriend — Anna Camp guests on the Dec. 26 episode of his new TBS comedy. She plays Heather, one of Brody's exes from his Harvard Business School days, and serves as a romantic stumbling block for the buttoned-up banker and his free-spirited new girlfriend, Jenny (Briga Heelan).

Heather causes trouble for the new couple by seeming to be Brody's ideal girl — even their singing voices are in harmony. "The second Skylar said Anna would do [the show], we said, 'We should probably do a karaoke episode,'" says executive producer Bill Lawrence. "There are four or five songs; it all culminates in a karaoke battle." And if Camp strikes a chord with viewers, Lawrence says she may pop up again later in the season.
