Former Hear'Say star Suzanne Shaw and her DJ husband Jason King are to separate.
The couple were an item for three years before they announced their engagement in August 2008.
They wed in in Christchurch, Dorset, in June 2009.
In a joint statement, the pair said: "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."
Suzanne, 30, used to be in a relationship with actor and singer Darren Day.
He left her on Mother's Day in 2005 only weeks after she had given birth to their son Corey, saying: "I don't do family."
Jason, 37, is of former JK and Joel fame on Radio 1.
