Alexander Skarsgård knows how to photo bomb at pic.

While his siblings were seen sitting on a couch, the True Blood star popped in the back corner of the shot and flexed his famous muscles for the camera.

I always say "when you've got a Porsche, you don't keep it in the garage."

While chatting with Conan O'Brien last month he explained that he became accustomed to nudity while growing up in his less-than usual household.

"My dad and his side of the family are old hippies," he revealed. "I was 14 the first time I saw my dad wearing pants. He was always naked."
