As we mentioned last month, Calvin Klein threw a big birthday bash for his boyfriend Nick Gruber and it turned out to be quite the star-studded event.
Guests who showed up to the ex-porn star's party included Donna Karan, Daphne Guinness and even Anna Wintour.
We're sure a good time was had by all, especially Nick.
