Giovanni Ribisi married his supermodel girlfriend, Agness Deyn, in a hushed little ceremony last weekend at the L.A. County Registrar’s Office. What makes it such big news is that not many people knew they were even dating.

Apparently the couple wants to keep their private lives to themselves, as they opted to marry in low-key t-shirts at the courthouse rather than in a big lavish wedding. They were spotted, however, by a reporter who just happened to be in the right place at the right time.

Ribisi has been acting since he was a child, appearing on the popular ’80s sitcom “My Two Dads” before moving on to more grown-up fare like “Suburbia” and “Saving Private Ryan” (my personal favorite of his films is “The Gift”. If you haven’t seen it, check it out on Netflix). Deyn, a model known for her boy-short blonde hair, has been on many major magazine covers and is a spokesperson for the makeup line Shiseido.
