Billy Eichner and Rhys Darby have landed guest-starring roles on The Millers, EW has learned.

Billy on the Street’s Eichner—who first tweeted a photo of himself on set with Margo Martindale on Wednesday—will play Leon, the ex-husband of Sean Hayes’ new character Kip, who has had a long-standing crush on Nathan (Will Arnett). To make Leon jealous, Nathan will pose as Kip’s new lover in the season premiere.

In the following episode, Rhys Darby (Flight of the Conchords) will play Martin J.S. Essex, a world-renowned writer of a Game of Thrones-type series of books who was a nerdy classmate of Nathan’s before becoming rich and famous. Unfortunately, he’s never forgotten the fact that Nathan was once mean to him when they were kids.

The Millers returns Oct. 30 at 8:30 p.m. ET on CBS.
