He has scooped Golden Globe awards for his role as FBI agent Fox Mulder in The X-Files.
And David Duchovny proved he was just as Agent Fox-y off camera when he went for a Christmas dive on holiday with his children, in Barbados on the festive day.
The shirtless X-Files star, 58, was every inch the action man when he went shirtless as he donned just a pair of khaki green swimming trunks.
Cooling off from the red hot temperatures of 29 degrees, the actor fearlessly dived head first into the sea.
Later, and refreshed from his swim, the American beamed from ear-to-ear as he stood on the boat surveying the festive joy going on around him.
While the actor is often hard at work on his latest TV or film project, the Golden Globe winner showed he knows how to unwind when he frolicked in the sea.
David was on holiday with his children — 19-year-old daughter Madelaine and 16-year-old son Kyd — whom he shares with his ex-wife Tea Leoni.
The dad's romance with Monique Pendleberry, 25, was revealed in October last year after they were first pictured together in Malibu in June.
They were last pictured in August together when the pair were hanging out on a Malibu beach under the summer sunshine.
