The Wolf of Wall Street star has been dating British moviemaker Tom Ackerley for around a year, and now fans are speculating the couple is heading down the aisle after Robbie was seen with a new piece of jewellery on her wedding finger.

The actress was snapped wearing the ring this week (begs15Jun15) during an outing in Toronto, Canada, where she has been filming new superhero movie Suicide Squad.

Robbie has yet to comment on the reports.
