The Crazy Ones Spoilers: Josh Groban To Guest Star

JOSH-GROBAN

CBS' new comedy The Crazy Ones starring Robin Williams has booked singer Josh Groban for a guest spot.

According to EW, Groban plays a guy named "Richie" who is a friend from Sydney’s (Sarah Michelle Gellar’s) past, who comes back into her life to repay a kindness. The problem? Sydney completely misperceives his intentions, and Simon (Robin Williams) intercedes to right the ship.

"In doing so, he gets an idea from Richie that lands a big account for the firm," adds a casting scoop intel. Expect for Groban to pop up in episode 6.

The Crazy Ones premieres Sept. 26 at 9 p.m. ET.
