Lorenzo Martone has confirmed he and fashion designer Marc Jacobs are married.
Reports last month said the pair had tied the knot but a representative for Jacobs denied they had, despite a wedding cake being delivered to the house.
But Martone, a Brazilian PR executive, told magazine Butt this week that the rumours were true.
He said: “In the end, we just had an intimate ceremony at a friend’s house with people who were already on the island.
“Although the official wedding documents won’t be signed till later this year, so legally we’re not married yet.”
They became engaged in March 2009 after a year together and held their ceremony on New Year’s Eve in St Barts.
