Kate Winslet - Winslet Punch-Drunk Over Dicaprio

KATE WINSLET is so close to her REVOLUTIONARY ROAD co-star LEONARDO DiCAPRIO, she would happily let him physically hurt her during a scene.

The pair teamed up for the first time in 1997 blockbuster Titanic, before working together for a second time in Winslet's director husband Sam Mendes' new movie.

Winslet shares a "rare" off-screen friendship with DiCaprio - and insists she is happy to go to extremes with him to make the perfect movie.

She tells Britain's OK magazine, "When we filmed difficult scenes we developed a secret language of our own. With our history we could do anything without feeling stupid.

"I would even let Leo physically harm me if it meant making a scene better, and I know he feels the same way. If we didn't have this rare friendship, I don't think we would be able to show that chemistry on screen."
