Has Margot Robbie pulled a Lara Bingle and had a secret wedding?

Former Neighbours star turned Hollywood heavyweight Margot Robbie might have secretly tied the knot.

Rumours of her possible marriage began after The Wolf of Wall Street actress appeared on The Tonight Show with Jimmy Fallon this week wearing a silver ring on her wedding finger.

The 25-year-old has been dating British assistant director Tom Ackerley since 2014, and she was also spotted wearing a ring on the same finger in Sydney in December.

While the Aussie actress, whose upcoming films include Suicide Squad and Whiskey Tango Foxtrot, is yet to officially confirm or deny the speculation, the evidence seems to speak for itself:

Look, a ring alone isn't proof of a wedding. Maybe it's the only finger that particular ring fits on, or maybe it's all a big publicity stunt.

But then again, Aussie celebs have a habit of pulling off a secret wedding (hello, Lara and Sam Worthington).
