Diddy’s Train has been going full steam all December, but it stopped for a little R&R in St. Barts, France, over the holidays. The music mogul was seen enjoying some family time on a yacht with his on-again-off-again girlfriend Kim Porter and their twin daughters D’Lila Star and Jessie James Combs. He will return to the U.S. to host a New Year’s Eve bash at LAX Nightclub in Las Vegas.
