What got between him and his Calvins? Eighty pounds.
John Luciano, who dated Calvin Klein ex Nick Gruber, is now a diet guru after dropping the weight in nine months.
“Because of the Nick connection a lot of people compared me to Calvin, and one Web site struck a nerve,” he tells us. “It said Calvin was 20 years older but looked 20 times better.”
Luciano is shopping a book, “Divorce Your Fat.” He also lost Gruber for good last year.
“The only thing I’ve written are checks to my boyfriends, but writing this book is far more rewarding,” he quipped.
