Add Christopher Guest to the long list of celebrities who love “Schitt’s Creek.”

“I’m happy for them,” Guest, who’s worked with Eugene Levy and Catherine O’Hara for over two decades, told Page Six at the Tribeca Film Festival on Saturday night. “They’re funny people.”

He added that he’s known Levy’s son and “Schitt’s Creek” creator Dan Levy since he was a little kid.

Following the announcement that Season 6 would be the show’s last, we asked if there was a chance for a new mockumentary starring Levy and O’Hara.

“I don’t really know,” he said. “I don’t really plan in the future. Things happen or they don’t happen.”

Both Levy and O’Hara worked with Guest on “Waiting for Guffman,” “Best in Show,” “A Mighty Wind” and “For Your Consideration.”

Celebrities including Jennifer Lawrence, Angelica Huston, Mariah Carey and even Bill Clinton have talked about the PopTV series.
