Kate Winslet Adorably Tears Up During Leonardo DiCaprio's Oscars Speech

Kate Winslet and Leonardo DiCaprio's friendship was in full force on Sunday night when The Revenant star hit the stage to accept his very first Oscar award.

Winslet -- who was also nominated for her role in Steve Jobs but lost out to The Danish Girl's Alicia Vikander -- told ET earlier this month that she had Leo's back at the Academy Awards, and she stuck to that promise.

When DiCaprio finally won for Best Actor after being nominated five times prior, his Titanic co-star couldn't hold back her tears of joy. Cameras cut to the 40-year-old actress and her husband, Ned Rocknroll, looking proudly at the 41-year-old actor on stage (about 2:23 minutes into speech). "To my friends, I love you dearly. You know who you are," DiCaprio said.

While the actor didn't mention Winslet directly, he did use his win as a platform to speak about a cause close to his heart, the environment. "Making The Revenant was about man's relationship to the natural world," he declared. "Climate change is real, it is the most urgent threat facing our species."
