To the stars! The 'Titanic' costars did not have to look very far for the stars while attending the 2007 Vanity Fair Oscar Party hosted by Graydon Carter. Leo has called his bond with the actress "unbreakable." In 2013 he revealed, "We were both just kids of 21 when we made 'Titanic' all those years ago. But, even then, Kate seemed more mature and worldly than I was. 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.”
