If you've ever wondered what goes on in a high-profile relationship between a 69-year-old fashion designer and his 22-year-old boyfriend—well, you're about to find out. Nick Gruber, who dated Calvin Klein for two years, is rumored to be writing a tell-all book—tentatively titled What Came Between Me and My Calvin.

"Yes, it's true that I'm writing a book," Gruber told the New York Daily News.

His ghost writer elaborated: "This is the only way he can get closure. He has a lot of secrets about Calvin and he has the right to tell people."

Gruber, a former porn star, dated Klein from 2010—yup, when Gruber was 20 and Klein was 67—until earlier this year. Klein was previously married to photographer Kelly Klein—they divorced in 2006.

Earlier this year, Gruber was arrested on suspicion of assault and cocaine possession.
