It's been 84 20 years since "Titanic" was king of the world, but the love between Kate Winslet and Leonardo DiCaprio still shines up like a new penny. Sure, their love has never been romantic in real life, as far as we know, but it is true love, and it has lasted a lot longer than their other relationships.

Leo and Kate are both in their 40s now, and they still hang out together. Speaking of their hang-out time, Winslet teased fans with some fly-on-the-wall gossip in a new interview with Glamour UK:

Kate Winslet on... her friendship with Leonardo DiCaprio...

"You don't even want to know the last conversation we had, because it was so funny and made me laugh so much. We found ourselves saying to each other, 'Can you imagine if the world really knew the stupid things we say?' I'm not going to tell you what we actually talk about, but yeah, we're very, very close and sometimes we do quote the odd 'Titanic' line back and forth to each other, because only we can, and we find it really funny."

Sigh. The preteen girl inside us just squeeeed loud enough to burst an iceberg.

After "Titanic," Kate and Leo co-starred as an unhappily married couple in "Revolutionary Road." You may recall watching them promote that movie on "TODAY," continuing to gush about each other when talking about how much they had changed, physically, since "Titanic."

Kate: "Well, I think I can speak for both of us: we have a lot more wrinkles. Don't we, darling? I'm proud of him, though. I can't say that you're taller, because you were always tall. He's a man now; look at him — he's just bigger. Physically you aren't that different; you're just less puny."

Leo: "She's still as beautiful and radiant as the day I met her. She is the consummate professional; she keeps pushing herself to an emotional truth when she's working. That's why I keep saying she's the best."

She is the best. She's also his best support system. You must remember how thrilled Kate was for Leo's many award wins for "The Revenant" last year:

Here's to 20 more years of friendship. May they stay foreeeever this waaaayyy, safe in their hearts, as their hearts go on and on.

Kate's new movie, "The Mountain Between Us," opens October 6.
