Leonardo DiCaprio

Kate Winslet's convinced the reason she and Titanic co-star Leonardo DiCaprio remain such great friends is because there was never any sexual attraction between them.

Although they starred in one of the greatest love stories of all time, the two never developed any romantic feelings toward each other.

She explains, "One of the most wonderful things about the relationship I had with Leonardo DiCaprio is that we were always just friends, not a flicker of flirtation.

"People wanted us to end up together in some way, but the kissing scenes in Titanic were very weird, like I was kissing my brother."

The British star admits that the two still provide each other moral support when they run into each other at big award shows.
