And last week, the Oscar-nominated actress, 33, seamlessly transitioned into the real-life role of bridesmaid, with Margot chosen to feature heavily in her best friend Britt Claxton's wedding. Fans were quick to note that this wasn't the first time Robbie had stepped into the supporting role of bridesmaid. In May 2017, she stood by her best friend Julia Koenig's side at her wedding in Hawaii. Two years later the actress supported good friend Anna MacKillop down the aisle to George Brya in a stunning Byron Bay ceremony. Margot also kicked up her heels at the celebrations at Rick Shores restaurant alongside the sizeable wedding party on day two.
