While talking to ET's Nancy O'Dell backstage at the Microsoft Theater in Los Angeles on Sunday, Brown explained that he has unsuccessfully tried to get in contact with Darden multiple times, and doesn't feel the need to reach out -- ever again.
"No, never, no," Brown said when asked if he had ever spoken to Darden. "I called him. I called him before, and he respectfully declined."
"I don't think it would be right to call him again," he continued. "He's a grown man living his life. He's gotta go with God, Mr. Darden. He's gotta do what he feels like doing."
That definitely didn't stop from Brown from enjoying his night, however. "I felt like I instantly began to float above the venue," Brown said of hearing his name being called as the winner. "It was surreal, because nothing like this has ever happened."
"It feels really, really great," he added. "It felt great to hear the appreciation of the audience, I felt loved. Like they really liked the performance. I could hear it."
Although Brown has never spoken to Darden, he previously revealed he had been in contact
with Darden's daughter, Jenee, "via Twitter and Facebook" during an interview with ET in August.
"She's been very kind in terms of sharing her thoughts about the performance," he said at the time. "As for her dad, I guess if it hasn't happened it probably won't happen, and that's OK."
Following Brown's win on Sunday, Darden's daughter took to Twitter to congratulate the actor. "I am in tears," she wrote. "Congrats to Sterling K. Brown! Much deserved."
Earlier in the day, she tweeted that even though she wasn't the one up for an Emmy, she still felt "so nervous."
and Sterling K. Brown's performances humanized my dad & Marcia Clark," another tweet read. "I'm proud & happy for them."
In addition to Darden avoiding any contact with Brown, he also revealed he had no intentions of even watching the hit FX series when ET spoke to him in March. "I can do without it," Darden said at the time. "Maybe in three years I can go back and read Twitter and not be offended. You know? Or angry. But you spend 20 years trying to get past something like that. You spend 20 years trying to move on with your life, and then it all catches up with you."
Meanwhile, Brown's co-star, Courtney B. Vance, who won the best lead actor in a limited series or movie Emmy for his role as Johnnie Cochran, was beaming with joy when ET's Kevin Frazier interviewed him post-show.
"I'm just grateful that, you know, we keep it real," he dished. "We keep it about what it's really about, and we keep it moving. If this didn't come to me, I would still be the same person. I'm still doing my thing."
"It's something that happens to other people," he continued. "We watch it. All of us watch and say, 'Oh, one year, one show wins everything.' Well, that happens to other people. Doesn't happen to me."
"It was surreal," Brown added. "It was surreal that we were actually a part of something that everyone was watching, and that everyone has embraced. It's a strange, amazing feeling."
Although Vance was surrounded by his co-stars, celebrity friends and wife, Angela Bassett, in celebration, there were a few other people on his mind -- their 10-year-old twins, Bronwyn and Slater.
During our interview, Brown explained he hadn't gotten a chance to call them yet. "They dragged me in here first," he joked. "I don't even have my phone! Angie has everything."
Luckily, ET was able to help. Frazier let Brown use his cell phone, and his kids couldn't stop screaming when daddy told them they were "live on ET!"
