The West End regular, TV star and Horrid Henry: The Movie actress married DJ King in 2009, three years after they began dating.
The couple has blamed their busy work schedules for the split.
A joint statement released on Monday (13Feb12) reads, “We had a wonderful time together and have great memories but constantly working away from each other added a lot of pressure and we have ended up growing apart.
“We are still friends and will be making sure we still have family time together for our son’s sake.”
King became father to Shaw’s son, Corey, after she split from his biological dad Darren Day in 2005, just three months after becoming a first-time mum.
