The network announced on Wednesday (Jan. 22) that “AD” patriarch Jeffrey Tambor will be reuniting with his on-screen son Will Arnett for an upcoming episode of new hit comedy “The Millers.”

In the episode, set to air this spring, Nathan (Arnett) and Ray (J.B. Smoove) pitch a Saturday morning kids program inspired by Tom’s (Beau Bridges) imagination to their station owner, Ed Dolan, played by Tambor.

On Wednesday, Arnett tweeted a photo of himself and Tambor in an embrace on set with the caption, “Reunited and it feels soooo good! @JeffreyTambor joins me on #TheMillers.”

The last time Tambor and Arnett shared the screen was last summer, in the Season 4 Netflix revival of “AD.”

“The Millers” airs Thursdays at 8:30 p.m. ET on CBS.
