"A while ago we took the difficult decision to separate but our main focus as always is to continue loving and supporting our children. This was not an easy decision to make, but we’re moving forward as the best parents we can be for our three beautiful children.
"We'll always be a loving family, we still have a great relationship and still live happily in our family home together."
The couple concluded their statement by adding: "We hope this now draws a line under any more unwanted and unnecessary intrusion into our private life.
