The Academy Award winner reveals if he's shared any advice with Leo.
Matthew McConaughey may have won the Academy Award for Best Actor over Leonardo DiCaprio in 2014, but the Dallas Buyers Club star says he is hoping for good things for his friend come Oscar Sunday.
"I haven't talked to him. I don't think he needs any advice," McConaughey told ET's Katie Krause on Thursday. "He had a wonderful performance, and there's really nothing he can do now. We'll see Sunday night."

DiCaprio's intense performance in The Revenant is going up against fellow nominees Eddie Redmayne (The Danish Girl), Matt Damon (The Martian), Bryan Cranston (Trumbo) and Michael Fassbender (Steve Jobs).
ET caught up with McConaughey as he was being honored at Unite4:Good and Variety's Third Annual Unite4:Humanity event presented by Karma for his work with his foundation, Just Keep Livin.
According to its website, Just Keep Livin was designed to "work with our nation's schools to reach the maximum number of teenagers with the greatest needs."

"We have 10,000 alumni, so we have 10,000 young men and women who have gone through our program, and are out now," McConaughey shared. "A lot of them still come back to help out. They learn exercise and nutrition goals. It's not a free ride. They're up at 4:30, packing up meals to give to needy families on the holidays. They're up at 4:30 to take a bus trip to go clean up a beach. When I was their age, I don't know if I would have given that much. I wouldn't have given my Saturday, but I'm amazed 100 percent of the kids who do."
