'Thought it could never get better than that day, but it did. Happy anniversary darling, Michael. With you, in my life, and Dylan and Carys, every day could be a twelve hour fantastic party at the Plaza in New York. Love you. #love #lovestrong (sic)'

It comes after Catherine revealed the key to the couple's long and successful marriage is that they listen to one another. 

After overcoming Michael's battle with cancer and her own battle with bipolar disorder, the brunette star says they are in a better place than ever.

The 48-year-old actress - who has Dylan, 17, and Carys, 14, with Michael - added: 'I'm very blessed. I have a husband who listens to me and I'm a wife who listens to him.

'That's why - although every marriage goes through its ups and downs, its times of adversity - we've come to a place where we couldn't be better. 

'I have a very healthy husband, a very healthy mother and two vivacious, healthy children. I think after that, everything just falls into place.' 

Michael also has 38-year-old son Cameron with ex-wife Diandra Luker. 

Meanwhile, Catherine - who's starring in Lifetime's Cocaine Godmother next year - launched her home collection Casa Zeta-Jones on QVC in September.
