The couple first met at a party in Sydney, Australia in 2002.
They got engaged in 2002 and married on the 15th March 2010 in Paris, France.
Before they tied the knot- Fisher converted to Judaism; "I will definitely have a Jewish wedding just to be with Sacha. I would do anything - move into any religion - to be united in marriage with him. We have a future together, and religion comes second to love as far as we are concerned." (Wikipedia)
She completed her conversion by 2007 after three years of study, took the name Ayala- the Hebrew name for doe and then received the approval of Baron Cohen's parents who are Jewish.
They now have two daughters; Olive (2007) and Elula Lottie Miriam (2010) and on the 1st October 2014, they announced that they were expecting their third child. Montgomery Moses Brian was born in March 2015.
Happy Anniversary Isla and Sacha!
