Rumors about Robbie getting hitched began to swirl over the weekend when the actress was seen arriving at an Australian airport wearing a shirt that said, "Say 'I Do' Down Under." Family and friends of the couple also shared some cryptic posts on social media hinting that there was a big occasion involving the pair underway.

The intimate ceremony took place on Sunday at a popular wedding venue in Byron Bay, a resort town in New South Wales, Australia. Robbie was reportedly walked down the aisle by her mother.

The 26-year-old Aussie actress and Ackerley, a British assistant director, first met in 2013 on the set of the WWII drama "Suite Francaise." They began dating a short time later, and reportedly got engaged this summer, though no official engagement announcement was made by the couple.

Congrats to the newlyweds!
