Helen Mirren, known for epic film turns and red-hot bikini body, turns 66-years-old today. Not only is she "The Queen" -- she won an Oscar for playing Queen Elizabeth II, she was appointed to the Order of the British Empire by Prince Charles -- that makes her Dame Helen to you, as well. Despite her respectable honors, the British actress, who stars in the summer blockbuster "Arthur" with Russell Brand, never misses an opportunity to titillate. She took it all off for Esquire Magazine, wearing only a Union Jack! Proving that barely dressed or fully clothed, Mirren works her wardrobe like the ultimate companion to her bodacious personality.

Take a peek in our gallery below to see how far Mirren has come since she had that ridiculous perm in the '70s. Happy birthday!

And don't miss Mirren's beauty transformation.
