Margot Robbie has seemingly confirmed she has tied the knot with British boyfriend Tom Ackerley.

Amid reports the pair exchanged vows over the weekend, the Suicide Squad star posted a photo on Instagram showing off a huge diamond engagement ring.

The Australian actress, who had never previously announced she was engaged, can be seen kissing assistant director Tom in the background.

The post came after Australia's Daily Telegraph reported that Margot, 26, and Tom got married in a romantic ceremony in Byron Bay.

Margot and Tom met in 2013 on the set of Second World War drama Suite Francaise.
