Kate Winslet recreated a famous "Titanic" scene on NBC's "Running Wild with Bear Grylls" last night, but that wasn't the only awesome moment from the episode.

The actress and mom of three also revealed how she instills confidence in her 14-year-old daughter, Mia — and why it's so important for her to teach Mia body positivity.

"When I grew up, I never heard positive reinforcement about body image from any female in my life," Winslet, 39, said. "I only ever heard negatives. That's very damaging because then you're programmed as a young woman to immediately scrutinize yourself and how you look."

Winslet continued, "And so I stand in front of the mirror and say to Mia, 'We are so lucky that we've got a shape. We're so lucky we're curvy. We're so lucky that we've got good bums.' And she'll say, 'Mummy, I know, thank God.' It's working, that thing that I've been doing. It's paying off."

The "Titanic" star also opened up about her definition of happiness, which she said "isn't a search for facial or physical perfection." She added, "It comes from inside."
