Leonardo DiCaprio helps Margot Robbie to cry during emotional filming scenes.
Margot - who starred opposite Leonardo in 'The Wolf of Wall Street' - always thinks of the actor dying in the sea as his character Jack Dawson in 1997 blockbuster 'Titanic' when she needs to convincingly weep for a role.
She revealed: "If I ever need to cry in a scene, I think of Leonardo DiCaprio as Jack dying in 'Titanic'. I would never tell Leo that. I'll kill myself if he ever reads this."
The 'Suicide Squad' star was being interviewed for W magazine's Best Performances of 2015/2016 issue, and another admirer who quoted the 41-year-old heartthrob as an inspiration is 'Girl With The Dragon Tattoo' star Rooney Mara.
The 30-year-old star gushed that she was in "love" with Leonardo at the age of 11 and would pretend they were married.
She said: "I didn't have posters of him, but I definitely had some cut-out pictures. I would write my first name with DiCaprio as my new last name to see how it would look."
Leonardo has been tipped as a potential Best Actor winner at the Academy Awards next month for his performance as American frontiersman Hugh Glass in 'The Revenant' - which is based on the true story of the events that unfolded during General Ashley's expedition of 1823.
Despite being nominated for five Oscars, the 41-year-old Hollywood star has always left the ceremony empty-handed so far.
