It's one of the most iconic endings to a film that people still love.
Rose (played by Kate Winslet) and Jack (Leonardo Di Caprio) desperately trying to survive after the sinking of the Titanic.
Kate was on The Late Show with Stephen Colbert and answered quick-fire questions such as whether she listens to Celine Dion's "My Heart Will Go On".
They also re-enacted the ending and fixed it a bit!
