Mr. Martone (left), with Mr. Jacobs.

Which of Marc Jacobs’s exes is Lorenzo Martone? The most recent one? Four exes ago? Not an ex at all? We can barely keep up. But we’ll have the chance to interrogate the hirsute gent at a private dinner MAC is throwing to celebrate a collaboration with fashion house Ruffian, with guests including Ruffian designers Brian Wolke and Claude Morais, as well as mega-stylist Mary Alice Stevenson. The after-dinner dancing will be done by guest DJ The Kids. Oh, Mary Alice, we’re a long way from the Upper East Side!

NoHo, invitation only.
