Margot Robbie believes the key to a successful relationship is "vulnerability."

The 'Suicide Squad' actress has been dating her boyfriend Tom Ackerley for two years after they met on the set of 'Suite Française' in 2014 and is convinced their romance is so strong because they're both so open.
She explained: "Over the years, you experience enough situations and your share of heartbreak that you tend to build up defensive walls.
"That happens to most people. The trick is to be able to learn from your previous relationships and become stronger, so that you can allow yourself to be more open and vulnerable again."
The pair currently live together in London but the 26-year-old beauty's highly successful career means she spends the majority of her time in the air.
She said: "My jet lag is getting a bit ridiculous now but you know, first world problems. 'Oh, I have to travel around the world. How awful.' "
And, although her career is going from strength-to-strength, Margot - who was first thrown into the limelight when she joined 'Neighbours' in 2008 - believes she may have "peaked too early" when it comes to her international success.
She explained to heat magazine: "Even I have to admit I may have peaked too early ... if someone's gonna pick between me and Emma Stone, they're going to pick Emma Stone."
However, the blonde beauty - who was born and raised in Australia - believes she's come a long way since her younger days - in both career and looks.
She added: "You should have seen me at 14 - with braces and glasses, gangly and doing ballet!"
