The love birds exchanged vows on March 15th with a traditional Jewish ceremony in front of close friends and family.
The ceremony was so hush hush, it managed to stay out of the press until a email from Isla was leaked.
In an email to pals, Fisher wrote, "We did it - we're married! It was the absolute best day of my life and in so many beautiful moments I missed you all so much. I thought of you as everything was happening, but Sacha and I wanted no fuss."
Sacha and Isla became engaged in 2004 and have an adorable 2-year-old daughter together named Olive.
Congrats to the happy couple!
