Musto Tears Into Calvin Klein

Fashion designer Calvin Klein is throwing a birthday bash for model Nicholas Gruber, who is rumored to be Klein's new boyfriend.

The duo have been seen out at several events together since last spring. For Gruber's 21st birthday, Klein, 68, is renting out New York hot spot Indochine Friday night, according to the New York Post's Page Six.

Village Voice columnist Michael Musto is not happy about Klein's rumored relationship with Gruber -- particularly their age difference. Musto wrote Friday that Klein is "embarrassing the whole community," specifically for hiding in the closet.

"Remember when you suddenly had a wife because, as AIDS made it uncool to be gay, you took the wussy way out and closeted yourself so you could sell more T shirts and perfume?" Musto wrote. "Now you've hooked up with that almost-21-year-old ex-porn star, Nick Gruber, and you're fawning over him as if this were real love and not a massive late-life crisis being acted out for the horrified masses. It's not going to work!"
