80-year-old Calvin Klein with his boyfriend Kevin Baker

Calvin and his younger boyfriend were spotted for the first time back in 2016, and they have since been photographed taking lavish trips together around the world and attending various elite red carpet events side by side.

FEMAIL has taken a dive inside their very private relationship – as well as Calvin’s past romances – and broke down everything we know about the notoriously secret couple.
