The model-and-actress admits she's a frequent member of the mile high club but says there's not much privacy when the time comes to get intimate.

The 23-year-old beauty said: "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?'"

Cara was being interviewed for LOVE magazine by her 'Suicide Squad' co-star Margot Robbie, in which they both discussed the most exciting places they'd had sex.

Margot, 26, also admitted to being adventurous with her love life and once got carried away on a jet ski.

However, she admitted it wasn't moving at the time as that would have made things too difficult.

She confessed: "That's aiming way too high. A non-moving jet-ski, but in the water."

The Australian star recently spoke about filming sex scenes with Leonardo DiCaprio in 'The Wolf of Wall Street' and admitted it was "awkward".

She said: "I'd done scenes where it's leading into sex or sex has just finished, but I hadn't done a start-to-finish sex scene like I did in 'Wolf'.

"There isn't an option. It's just like, 'This is what you need to do - get on with it.' The sooner you do it, the sooner you can stop doing it. It's so awkward."
