"After six years together, they have recently decided to formalise their separation.
"Despite this being the end of their marriage, they love, support and respect each other as both parents of their son and as family."
Orlando, 36, and 30-year-old Australian model Miranda started dating in 2007.
They were married in July 2010, just one month after announcing their engagement.
Miranda gave birth to their son Flynn on 6 January, 2011.
The couple were last pictured together on 8 October, and they made their last public appearance on 19 September at the Broadway opening of Romeo and Juliet, which Orlando is currently starring in.
