Despite the controversy surrounding this year's Oscars, Kate Winslet wouldn't miss it for the world.

The 40-year-old actress -- who is nominated for an Academy Award for her role in Steve Jobs -- told ET that while some of her peers have chosen to boycott the ceremony due to the lack of diversity among the acting categories, she wants to be there for her friend and former co-star, Leonardo DiCaprio.

DiCaprio, 41, is up for his fifth Oscar for his role in The Revenant and Winslet is confident he could finally win. "For me, it wouldn't be the year not to be as close to Leo in that moment, should it happen for him," she gushed while promoting Triple 9, out Feb. 26, in London.  "Leo, I've got his back. He doesn't need me to tell him."

Fans saw just how much Winslet adored her Titanic co-star when she won a Golden Globe in 2009 for her role in Revolutionary Road, which also starred DiCaprio. "Leo, I'm so happy I can stand here and tell you how much I love you and how much I’ve loved you for 13 years," she said in her acceptance speech, causing the actor to tear up. "And your performance in this film is nothing short of spectacular. I love you with all my heart, I really do."

Clearly, we can't wait to see what will happen if DiCaprio wins on Feb. 28. "The sense of good will behind Leo is the thing that's touching me the most," she exclaimed. "I mean, literally, people in the street go, 'Hey Kate, you know it's Leo's year,' and I'm like, 'Hip, yeah! I think it really might be!'"

Winslet added, "That is really quite moving [because] he's an actor who's been around for years. He's been doing this since he was a teenager, and the fact that people like him as much as they do -- that they want this for him -- that's really amazing."

The actress also told the ET that she wants to attend the Oscars to support her fellow female nominees. "It's been an amazing year for film, my industry, for women [and it's] important to acknowledge," she continued. "[I'm] proud to be included."

While Winslet has a special bond with DiCaprio, her teenage daughter, Mia, is pretty smitten with her mother's co-star in The Dressmaker, Liam Hemsworth. When  ET asked how her daughter felt   about Hemsworth's rumored rekindled romance with Miley Cyrus, Winslet thought her she'd "probably be very disapproving."

The actress quipped, "Well, I just think she wants Liam all to herself, quite frankly."
