They were engaged in New Years 1999 and married in November 2000 and bonded over golf, acting and even shared a birthday, albeit 25 years apart.
The couple are parents to 13-year-old Dylan and 10-year-old Carys.
They have had a tough couple of years with Catherine supporting Michael through throat cancer in 2011, which is now in remission, and he helped her through her stint in rehab for bi-polar disorder.
It seems that they were well suited but we will never know the full story and maybe for them it is the right choice. It got me thinking, can divorce sometimes actually be a good thing?
Have you been through a divorce and realised it was actually for the best?
