Kate and Leo's Epic Friendship in Their Own Words

The adorableness didn't stop there, since Leo gushed to Ryan Seacrest on the 2009 Golden Globes red carpet: "We've been great friends for a long period of time. We were actively looking for something to do together. It felt really natural. She's my homie."

Things got even sweeter inside the show, when Kate won for her role in Revolutionary Road and included a heartfelt message to Leo in her acceptance speech.
