It really was Leo's year.
The 41-year-old actor finally took home the Oscar everyone wanted him to have.
Today, the six-time nominee won his well-deserved Best Leading Actor Academy Award for his role in The Revenant.
Naturally, Leo - a passionate environmentalist - took the moment to draw attention to climate change.
"Climate change is real, it is happening right now. It is the most urgent threat facing our entire species and we need to work collectively together and stop procrastinating," he said. "I thank you all for this amazing award tonight. Let us not take this planet for granted, I do not take tonight for granted."
