Kate Winslet and Leonardo Dicaprio have been very close friends for the past 15 years. They have always been there for each other, in the bad times as well as in the good ones. The 36-year-old Inception actor recently supported the 35-year-old actress after her split from her husband Sam Mendes.

In an interview given to Vogue, Winslet said that Leonardo was her rock. "Lots of male friendships begin as a cheeky snog. Or a little undercurrent of flirtation. But Leo and I? No. He's my rock. I don't know what the f**k I would have done if I hadn't had him."

The two actors costarred in 1997's Titanic and 2008's Revolutionary Road.
