Leonardo DiCaprio & Armie Hammer: Temple Twosome

Leonardo DiCaprio and Armie Hammer get to work on their upcoming film, J. Edgar, on Monday (March 28) in Alexandria, Virginia.

The two actors shot scenes on the steps of the George Washington Masonic Memorial.

Leo stars as FBI boss J. Edgar Hoover, while Armie plays his number two man and rumored secret lover Clyde Tolson.

E! Online reports that they’ve already filmed their “passionate” lip-locking scene!

“[They did] more [takes] than [director Clint Eastwood] normally does. They wanted to make it right. It’s a more involved scene than just the kissing. It was so sexy,” said one source.
