Margot Robbie confirms her marriage on Instagram

The 'Suicide Squad' star has taken to her Instagram account to share a picture of herself and new husband Tom Ackerley who she has been dating for three years - complete with her pear-shaped diamond wedding ring. The image of the couple is blurred out apart from her left hand which features the huge sparkler on her wedding finger, which she is pointing towards the camera. Margot, 26, and Tom tied the knot in Coorabell, near Byron Bay, where around 50 guests were in attendance. The wedding began at 4pm and concluded with a disco which finished around 11pm. Margot and Tom were so determined to keep their big day a secret they even told guests to meet at different locations, from the Gold Coast to Byron Bay, before they were collected by bus and transported to the venue. Guests were also asked to hand in cameras and mobile phones to ensure a social media blackout was adhered to. The pair are said to have got engaged over the summer and managed to keep it a secret. Attendees at the nuptials included the star's brothers Lachlan and Cameron, and her sister Anya. But the actress is estranged from her dad Doug so mother Sarie is thought to have given her away. Margot was spotted landing in Australia last week with a T-shirt on which read: "Say 'I do' Down Under." The couple met on the set of movie 'Suite Francaise' and live together in London.
