Leonardo DiCaprio and Kate Winslet relax in sunny Saint Tropez

Twenty years after being the main actors in the classic "Titanic" movie, Leonardo Di Caprio and Kate Winslet were recently reunited with Saint Tropez and it was almost as if no time had passed since they starred in Titanic together. The pair have been friends since meeting on the set of the famous 1997, when they played in Titanic, a film that has grossed $ 2billion. Di Caprio spent a day relaxing with Kate. The two friends were seen chatting on the deck of Leo's villa before they walked back into the house with their arms wrapped affectionately around each other. The pair later attended Leo's foundation charity gala, where they auctioned off an intimate dinner with them in NYC as the top fundraising prize at a gala for the Leo's environmental foundation. The Leonardo DiCaprio Foundation is dedicated to the long-term health and well-being of all Earth's inhabitants, and has given $ 80 million to environmental causes and organizations since 2008. Leonardo DiCaprio, Kate Winslet and Billy Zane were all smiles at this gala. Billy Zane, who has interpreted the role of Cal Hockley, the fiancé of Rose (Winslet), in "Titanik".Rose leaves from him, after meeting scrappy, working class artist Jack and falling for him, while aboard the doomed luxury liner. Despite close bond, Winslet- DiCaprio, she was quick to deny she had ever enjoyed a romance with Leo, back in 2014, while Leo when he asked by Oprah said that Winslet was the best person he had kissed: "Oh boy ... There's going to Be some mad actresses ... I'm just going to go with Kate Winslet" The pair have been very open with their friendships in the past, attending a number of high profile events and awards together over the years. Cate Winslet explained their friendship only worked because they had no romantic interest - meaning they could always support each other both in their careers and personal lives. She explained: "I think the reason that friendship works is because there was never any romantic thing". 'It's so disappointing for people to hear that, because in the soap opera of the Kate and Leo story we fell in love at first sight, but actually we never did. He always saw me as one of the boys; I've never really been a girly-girl. Kate is currently married to Ned Rocknroll, who she wed in New York in 2012, while Leo has had a more hectic love life - dating the likes of Gisele Bündchen and Bar Rafaeli etc.
