Calvin Klein's Ex Busted for Cocaine

It's being reported that Calvin Klein's ex-boyfriend Nick Gruber has left town and entered rehab. According to the New York Daily News the word is Klein is paying for Gruber's stay at an undisclosed rehab in Arizona. This is after Gruber was arrested last week for hiding cocaine in his undies. Gruber split from the 69-year-old fashion mogul in January.

According to the Daily News Gruber was about to move to California to pursue a career in reality television but was arrested the day before for punching Calvin Swint, who appears to be an intern for New Jersey Sen. Frank Lautenberg. The police later found a stash of what appeared to be cocaine in Gruber's underwear.

Gruber is a former underwear model, but Gawker, has apparently dug up some dirt linking him to gay porn under the name Aaron Skyline.

Klein is no stranger to rehab as he also underwent his own stint in 1988.

Gruber faces 3 criminal charges, which includes assault, resisting arrest and possession of a controlled substance.
