Good things come to those who wait.
E! News has confirmed that the low-key couple swapped vows in a small, private Jewish ceremony in the City of Light on March 15, with their 2-year-old daughter, Olive, among the half-dozen on hand to witness the vow swap.
Though that may be because they were given "very little notice" prior to the big day in order to keep the ceremony as quiet as possible.
"We did it—we're married!" Isla reportedly boasted in an email sent to friends (who apparently saw fit to forward it to the tabloid) the next day, per Australia's Woman's Day. "It was the absolute best day of my life and in so many beautiful moments I missed you all so much."
