Nearly two decades since the movie's release, Winslet dropped a bombshell during an appearance on "Jimmy Kimmel Live!"

The British actress admitted Monday night that she thinks DiCaprio's character Jack, a poor man from Wisconsin who won a ticket for a trip on the regal boat during a poker game, could have lived.

"In a way, you let him freeze to death in the water," Kimmel said.

"I agree. I think he could've actually fitted on that bit of door," Winslet said.

The 40-year-old later talked about her close relationship with DiCaprio, saying the two laugh about the fact that fans get so overwhelmed by "the Jack and Rose thing" -- the love story and relationship the actors' characters had in the legendary movie.

"People are always so excited to see Leo and myself in the same space," she said. "It's quite endearing."
