Alexander Skarsgard poses nude on a toilet in Antarctica

Jan. 8 (UPI) -- Prince Harry wasn't the only sex symbol heating up the Antarctic on last month's Walking With the Wounded charity trip to benefit wounded veterans. He was joined by True Blood star, Alexander Skarsgard, who just shamed anyone complaining about the Northern Hemisphere's so-called polar vortex.

On Tuesday, one of Skarsgard's teammates shared an Instagram photo featuring the 37-year-old Swedish actor naked on a toilet in Antarctica.

"#southpole -30C What are you reading Alex?," wrote Inge Solheim. "The script for season 7 of #truebloodHBO ? :-)"

The photo looks like a reference to Skarsgard's unusual nude scene in the sixth-season finale, in which vampire Eric reads a book on a lounge chair in the snow.
