Kate Winslet may have just had a child with her third husband, Ned Rocknroll, but there are plenty of Titanic fans still waiting for the 38-year-old actress to get together with her occasional co-star and best friend Leonardo DiCaprio. Though both actors have denied ever having a romantic relationship, Winslet told Pop Sugar at the premiere of her latest film, Divergent, that DiCaprio is probably the "love of her life." Asked to choose between Divergent hunk Theo James and DiCaprio, Winslet smiled coyly and said, "Leo is my love of my life." "How could you possibly ask me that question?" she added. "If I said Theo over Leo, he would never let me stay the night at his house again." DiCaprio told the Express in 2013 that Winslet has been his "closest friend" since they met on the set of Titanic, though they've never dated. "I cried on her shoulder many times as we found the demands of filming under the director James Cameron so tough. We have never not been friends since that time. I speak to her all the time. But friends -- not lovers."
