Breaking up may be hard to do, but the aftermath? Perhaps not so much. SNL co-stars and newly minted couple Abby Elliott and Fred Armisen — who is still pretty fresh out of his separation with Elisabeth Moss — engaged in some PDA on a date at Riposo’s uptown location. Downtown at the Lion, Jim Carrey (who split with Jenny McCarthy a few months back) and Noah Emmerich took two ladies on a double date. The rest of this week’s celebrity dates, birthdays, and random lunches, straight ahead.
