“Suicide Squad” deadly-duo Margot Robbie and Cara Delevingne, who plays Harley Quinn and Enchantress in the highly-anticipated upcoming super-villain movie, have revealed some of their naughty secrets in a LOVE magazine interview.

The two are not only “bad girls” in the movie but also in real life. They opened up on their sex lives to the magazine, revealing the craziest places they have had sex. While 33-year-old Delevingne, who is dating St. Vincent, loves to have sex in planes, Robbie is more of a mermaid, indulging in action in the sea but on her surf board.

“I've had sex in planes a lot. But I’ve always been caught. It's super-hard not to get caught. I had sex in the chair on the plane and there was a guy watching. We ended up telling the air stewardess what was happening. Like, ‘This guy keeps staring at us. Can you tell him to stop?’” Delevingne revealed in the interview, writes Mirror.co.uk.

However, 26-year-old Robbie admitted she became pretty adventurous on a jet ski though it wasn’t moving when she spurred into action.

“That's aiming way too high. A non-moving jet-ski, but in the water,” Robbie revealed.

She was recently photographed secretly during a surf board fail while vacationing in Hawaii with boyfriend Tom Ackerley.

Commenting on her character Quinn’s outfit in the movie, Robbie said that she tried about a hundred different versions of the outfit and costume designer Kate Hawley finally came across a Debbie Harry photo and that was how they finalised Quinn’s costume.

“What she’s wearing – I don’t care how revealing it is if she wore it because she liked wearing it. I don’t want it to look like she wore it because she wants a guy to think she looks hot in it. No way,” Robbie told LOVE.
