Calvin Klein's Ex Arrested for Drugs Rachel Krause, TheFrisky.com If 69-year-old Calvin Klein's (former) relationship with model Nicholas Gruber wasn't weird enough already, it just got a little weirder: Gruber, 22, was charged with misdemeanor assault, resisting arrest, and possession of a controlled substance early Tuesday morning after he allegedly assaulted a man in his Greenwich Street penthouse. The 20-year-old victim, who had been at the assailant's house for a "get-together" of sorts after Gruber took him home following a night out, suffered injuries to the face during the 4 a.m. scuffle. When apprehended by police, Gruber didn't go easily, flailing "his arms in an attempt to avoid being cuffed" and shoving "his hand into his pants trying to conceal something," sources said. That "something" was cocaine, which authorities discovered hidden in his underwear when he was strip-searched at the police station. NY Post A Guide to the Incredible Women on 'Game of Thrones'
