The 22-year-old model, who has been dating the designer sporadically for several years, was arrested after he allegedly punched pal Calvin Swint in the early hours of Tuesday (24Apr12).

Gruber allegedly resisted arrest and officers found cocaine at the scene, and he appeared in Manhattan Criminal Court on Tuesday evening to answer to three charges.

On Wednesday (25Apr12) Gruber left his apartment to check into rehab, according to New York Post gossip column Page Six.
