'Titanic' Stars Leonardo DiCaprio and Kate Winslet Together in Saint-Tropez

Leonardo DiCaprio and Kate Winslet will always be linked whether they're near, far or wherever they are ... but it's always best to see them together.

The famous "Titanic" couple hung out at Leo's villa in Saint-Tropez, France in late July ... and the 2 are clearly still very tight.

Kate was visiting to attend the Leonardo DiCaprio Foundation annual charity gala, but the old friends and fellow Oscar-winners found some time to chill by the pool and catch up.

And our hearts will go on.
