The 69-year-old sparked an international scandal when he split up with his long-term partner Mia Farrow in 1992 after falling for her adopted daughter. Allen later married Previn, 35, and the couple have two children.
Yet, the MANHATTAN film-maker is unabashed when he admits that his relationship with Previn is paternal and he enjoys the power his successful life gives him in their relationship.
He says, "(Our marriage) has a more paternal feeling to it... I love to do things to make her happy. She loves to do things to make me happy."
Despite the controversy it caused, Allen has come to view Farrow's discovery of his nude photographs of Previn as "one of the great pieces of luck in my life".
He adds, "All the women I went out with were basically my age. Now, here, it just works like magic.
"The very inequality of me being older and much more accomplished, much more experienced, takes away any real meaningful conflict."
