Marc Jacobs & Lorenzo Martone Hit The Beach... With Rachel Zoe! (PHOTOS)

Marc Jacobs seized the holiday season to show off his chiseled physique on the pristine beaches of St. Barts yesterday -- with surprise guests!

Accompanied by his beach buddy, ex-fiance and HuffPost blogger Lorenzo Martone (vacationing with your ex: risky move?), Marc bared his quirky tattoos in a navy bathing suit as the pair soaked up some December sun together.

We're especially loving the Birkin bag plopped nonchalantly on the sand. Must be nice!

Marc is, of course, famous for his outlandish ersatz beach gear: he previously toted a $10,000 Hermes Kelly purse to the shore as a beach bag, and in 2009 he and Lorenzo accessorized with Louis Vuitton monogrammed bags and towels on the St. Barts sands.

And things got even more fashionable when fellow vacationer Rachel Zoe dropped by with baby Skyler Berman, whom the pair oohed and ahhed over. Rachel later sat down next to them for some rays.

Jacobs and Martone called off their engagement back in July 2010, but it looks like they're still chummy. Perhaps a reunion is in the works?
