Marc Jacobs & Lorenzo Martone: St. Barts Holiday Break!

Marc Jacobs arrives in St. Barts on Monday (December 26) for a post-holiday vacation.

The 48-year-old fashion designer was joined by his ex, Lorenzo Martone.

Lorenzo recently spoke with Dirty magazine about his feelings on monogamy.

“I do [believe monogamy is possible]. However my longest relationship was only 2 and a half years. A lot of couples I know that have been together for 15 or 20 years have healthy open relationships. I often wonder if that influences a relationship’s longevity,” Lorenzo told the mag, adding that while he’s single at the moment, he and Marc are still best friends.
