The Revenant actor, who walked away with the best actor prize at the BAFTA Awards Sunday, gave a shout-out to Titanic costar and longtime pal Kate Winslet for her unwavering support amid his triumphant awards-season run.
"My main groupie?" DiCaprio, 41, said with a laugh when reporters backstage dubbed Winslet just that, while asking about the outpouring of support he's received from her and many others.
"It feels amazing," he explained. "Honestly, I have a true love for cinema. I have, ever since I was a young teenager ... So to have worked in this industry ever since I was 13 years old, having done 20-something movies and to be here now, and have it be for a film like this that we worked so very hard on, it feels amazing. It feels fantastic."
He then added: "And Kate – that's my homegirl!"
Winslet, 40, for her part, spoke out about DiCaprio at the BAFTAs – while answering one of life's eternal questions: Could Jack have fit on that door with Rose as the Titanic sank in the background?
Winslet and DiCaprio just can't escape the debate, even 19 years later, to the point where Winslet was even asked why there's so much fuss about the iconic door while in the BAFTA Awards press room.
"Do you know what's lovely? So much time has passed that it doesn't matter what I say now," Winslet said. "It's not going to be a story that causes a huge furor. It'll just be something that makes people laugh."
"Thank God for time and the passing of it, that's all I can say!"
Winslet, who took home the BAFTA award for best supporting actress for her role in Steve Jobs, says DiCaprio doesn't feel quite the same about that piece of wood.
"He doesn't care about the door," Winslet says.
But even though Mythbusters took a scientific approach to settle the debate once and for all (determining that, yes, if they put Rose's lifejacket under the door, they both could've survived), the controversy lives on.

"I think he could have actually fit on that bit of door," she said on Jimmy Kimmel Live! Feb. 1.
Following their respective BAFTA victories, both DiCaprio and Winslet head into the homestretch for the Academy Awards on Feb. 28, where they're expected to put up some stiff competition in their categories.
