Margot Robbie says Leonardo Dicaprio is a great ''screen kisser''.

'The Wolf of Wall Street' actress admits she left her friends disappointed when she shared the details of her intimate encounters with her co-stars as they were hoping for ''fireworks''.

She said: ''I'm still pinching myself. Leo has always been my favourite actor and he became this wonderful big brother. All of my girlfriends interrogated me and asked, 'Is he an amazing kisser?' I'd say, 'All I know is his screen kissing is great.' Then they'd get upset and say, 'Tell me there were fireworks.' There weren't. You do the takes in 17 hours, and its just hot and sweaty.''

Margot had to get naked for her big screen breakthrough, but admits she had to take her clothes off so many times she wasn't worried about it at all.

She added to People magazine: ''At first I was absolutely petrified. By the end there was so much nudity, nobody was fazed about undressing. I have no concept of modesty anymore.''
