Sixteen years ago, back in 1997, Leonardo DiCaprio and Kate Winslet started in one of the biggest blockbusters in history, Titanic. The two have remained extremely close throughout the years and have admitted to have walked away with lifetime friendships after filming Titanic. Eleven years later, in 2008, the two stars re-united in Revolutionary Road.

Leonardo, now 40-years old, remains one of Hollywood's most eligible bachelors, and after all their relationships -- including Kate's marriage and separation to Sam Mendes and Leo's string of model relationships, including Gisele Bündchen.

During a recent interview, Leo was asked about Kate Winslet's nickname for him, "Farty Leo" which he laughed off. "She never says that to my face. She's the greatest person. She's so genuine. I love that girl. She has a brand-new baby and is in love" said Leo.

Winslet just gave birth to her third child, son Bear, with third husband, Ned Rocknroll. Kate's other kids are Mia, 12 and Joe who's 9.

The feeling of adoration and fondness is something Kate also bestows upon Leo. Kate has previously referred to Leo has her "rock" and was all praises when it came to her Titanic on-screen lover who supported her through her split from Sam Mendes.

She told Vogue, "He knows me better than anyone else in the world. 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."

Leonardo is dating Victoria Secret model Toni Carrn and has been recently linked to newly single Miranda Kerr following her split from husband Orlando Bloom. It was reported that DiCaprio and Kerr were spotted dining together last month. This rumor quickly fizzled when Leo and Toni were seen publicly displaying affection at Kanye West's concert in New York a few days later.
