Though reps for Margot have yet to confirm reports of the wedding, she was photographed arriving at Gold Coast airport last week wearing a T-shirt that read "Say 'I Do' Down Under." And you don't wear a shirt like that for no reason...
The Telegraph reports that Margot's mother was on hand to give the bride away at the Byron Bay wedding, while her sister was the maid of honor.
