Woody Harrelson goes skinny dipping with Owen Wilson

Woody Harrelson strips off for skinny dipping with Owen Wilson

Woody Harrelson has been snapped stripping off naked and going for a skinny dip while out with Owen Wilson in Miami.

The Natural Born Killers star, 46, cooled off with an impromptu skinny dip while hanging out with pal Owen Wilson in Florida as he films Marley & Me with Jenifer Aniston.

While Wilson kept his modesty – and his shorts on – daring Harrelson decided to Free Willy.

Over the scorching weekend, the pair enjoyed the men's and ladies' singles finals at the Sony Ericsson Open in Key Biscayne.On Saturday, the actors had front row seats to watch Serena Williams beat Serbia's Jelena Jankovic, and reclaimed their prime position on Sunday to see Russia's Nikolay Davydenko win against Spain's Rafael Nadal.

After working up a sweat under the blazing sun, Harrelson couldn't wait to get back to his waterfront Miami home - and strip for a cooling down in the Atlantic.

But it wasn't just a naked swim he enjoyed. When the actor emerged from the sea – showing off his white backside – he proceeded to engage in a nude workout, doing press-ups in the buff.

Wonder what Owen made of it all.
