One of the clan! Margot Robbie poses with boyfriend Tom Ackerley at family nuptials after recently denying wedding rumours

She has been dating her director beau Tom Ackerley for three years.

Clad in a breezy strapless maxi dress, the 26-year-old beauty was spotted in several social media snaps uploaded by Tom's brother James, in which she is seen posing in a breezy floral maxi dress.

It comes after Margot hit back at rumours that she and Tom had tied the knot in secret.  

The couple sparked rumours of a secret marriage after they were seen wearing matching gold bands while Margot filmed Suicide Squad in Toronto last June. 

According to Woman's Day, a friend of the pair claimed that: 'It is well known within their friendship group that they got married - people refer to them as husband and wife.

'Their own friends talk about it to other people. They did it on the down-low, without many people around them,' they added.

Previously, Margot revealed the secret to keeping the spark alive in her three-year relationship with her long-distance lover Tom.
