Marc Jacobs has split from his partner and reputed "husband," New York fashion PR Lorenzo Martone, the latter confirmed via Twitter. "We are not together, haven't been in 2 months," he wrote, declining further comment.

Martone was responding to a quote from Jacobs published on British Vogue's Web site, in which the designer said simply: "No, I am not getting married."

The couple caused widespread confusion by referring to each other as being "married" following a "wedding"-- really, a non-binding commitment ceremony -- on the Caribbean island of St. Barths over last New Year's.

Jacobs's rep later clarified that the event was simply a "party," despite the fact that it featured a wedding cake topped with likenesses of the couple.

Martone said in an interview with a gay magazine in February: "We just had an intimate ceremony at a friend's house ... although the official wedding documents won't be signed till later this year, so legally we're not married yet."

Privately, the couple told friends in New York's fashion community to expect a lavish, "official" wedding sometime later in 2010.

When StyleList met Martone during the last New York Fashion Week, he introduced himself as Jacobs's husband. But he said to a different guest later that same evening that he and Jacobs were not together, but trying to work through their difficulties.

Even while appearing at public events with Jacobs, such as June's amfAR Inspiration Gala at the New York Public Library, in recent months Martone was frequently been seen in the company of other men.
