The acid-tongued Chanel boss is at it again.
Karl Lagerfeld thinks there's only ever been one Pope who is "chic".
The esteemed designer, 79, is starring in a four-hour documentary slated to air on September 7 on Vox in Germany.
Entitled Mode Als Religion, television journalist Martina Neuen follows Karl as he goes about his daily fashion routine - preparing for shows and shoots over a 16-month period.
In the documentary, the Chanel star refers to himself as a “fashion missionary” and talks about “fashion popes”.
“The only pope I thought was chic was Pius XII. Even though he may not be remembered for his popularity, I thought he was elegant," he explains in the documentary, according to WWD.
"And Pope John XXIII was the most charismatic; you can keep all the others."
The TV special enlists German neurologist Christian Elger to perform an experiment to "see how the brains of a Catholic priest and a devoted fashionista responded in the face of their respective 'religions.'"
“The emotional reactions are the same,” Martina smiled.
The brainchild behind the programme also admitted that the documentary is "a bit tongue-in-cheek".
It also features interviews from those who have worked with Karl, including Claudia Schiffer, Linda Evangelista, Diane Kruger, Sarah Jessica Parker and Milla Jovovich.
The footage is taken from all over the world, including London, New York City and Singapore.
Martina says she was instantly taken aback by the eccentric designer after meeting him in 1999.
“He’s the most impressive person I’ve ever met,” she gushed. “He’s a true individual, and there’s a lightness of being around him.
