And you thought the polar vortex was cold! A new photo of 'True Blood' hottie Alexander Skarsgard gives new meaning to the word.

The actor, in Antarctica last month for the Walking With the Wounded Challenge, posed for a hilarious pic sitting on a toilet in the otherwise unspoiled snowy tundra. He's reading a book and looks lost in thought. The best part, though? He's totally nude, except for a pair of big black boots and sunglasses!

The photo was posted on Tuesday (Jan. 7) on Instagram by Inge Solheim, who guided ASkars' team in the charity challenge. "#southpole -30C What are you reading Alex?" Solheim wrote alongside the image. "The script for season 7 of #truebloodHBO ? #alexanderskarsgard."

'True Blood' fans will recall that Skarsgard was last seen in a similar pose in the season 6 finale of the HBO series. He took it ALL off for the show's final scene, sunning himself while reading a book on a snowy mountainside.

Nudity is no big deal for the 6-foot, 4-inch Swede, though. As he said on 'Conan' last year, "My dad and his side of the family are old hippies. I was 14 the first time I saw my dad wearing pants."
