In a release, series co-creator Carter Bays said of his guest star, "Katy is a tremendous talent, and we are delighted to be able to work with her." The episode would be called "Oh Honey" but its release date is still unknown. According to CBS, Honey is the cousin of Jennifer Morrison's Zoey and "the gang resorts to calling [her] 'Honey'."
Perry isn't the first singer to land a role on the series - Britney Spears, Nicole Scherzinger and Carrie Underwood have all made scene-stealing cameos in the show.
This would be Perry's first appearance in a primetime sitcom. She previously played with Elmo on "Sesame Street" and got slammed for her revealing outfit. In response to the criticism, Perry appeared on "Saturday Night Live" with a good view of her cleavage.
