The 68-year-old Klein is throwing one major party at NYC’s Indochine. In fact, he’s buying out the entire restaurant for the night to keep things private.
As for his beau, Nick Gruber, the two have been dating since last year.
And Gruber, who will be turning 21-years-old, will have his party on January 21st with the invitations reading:
"In the spirit of the New Year and in celebration of Nick Gruber's birthday, please join Calvin Klein for dinner and drinks at Indochine Jan. 21 at 9 p.m. It will be the hottest ticket for New York's gay and fashion elite."
Oh to be 21 and have a rich, successful boyfriend!
