Fully half of your post was about Klein frequenting clubs & saunas. The relevance of that to your main point (the writing of the book?) was what I found elusive.

It is called "connecting the dots" which you seem to have trouble doing.

Anyway, Calvin Klein is not concerned about any "expose" in any book his former namorado might write. Klein will continue his merry way and will most likely look upon the former "love interest" as a pleasant chapter, among many.

I agree. The only regret CK may have is his folly in throwing a party to introduce the boy to all his friends.

Another day, another interview with Calvin Klein boytoy Nick Gruber saying he’s not gay. Because that’s false information. “I don’t believe in labels, I believe in what my heart tells me I love. If people say, ‘What are you?’ I say, ‘I’m not gay. I’m straight, but I believe in love.’” He also says he’s only had one relationship with a man, Klein. As for John Luciano, “No. He was only a friend. It was never a relationship about ever being together.” Which doesn’t explain why John said“The most intimidating thing is having sex with your boyfriend and pulling down his pants and his ex-boyfriend’s name is staring you right in the face.”

Speaking of Gruber, Michael Lucas had him ejected from his corner of the uber-gay Fire Island Ascension party after Gruber caused a disturbance, screaming at people touching him while declaring he’s straight. I’m not a fan of Lucas, but when Gruber tried to pull a “don’t you know who I am” Lucas responded with “I called over to security and had him hauled away without his feet even touching the floor.”

Now Nick Gruber has done an online reality show and it has surfaced. . .

OMG. What a train wreck this is going to be.
