Werner Boehm was introduced to the 10-year-old female baboon while filming a music video.
He said: "It was love at first sight. The monkey is extremely musical and can even play the piano. We're on the same wavelength."
But his 31-year-old wife Susanne was not amused and moved out after Boehm allowed the pet to share his bed and dismissed the animal's demolishing of the furniture as "harmless fun".
She said: "I gave him the choice: The monkey or me. He chose the monkey. It's incredibly painful to know that some baboon is more important to him than I am."
