If you’ve spent any time on the country music side of the internet lately, you've probably seen that one video. It’s grainy, intimate, and feels like you're peeking through a window into someone’s living room. Keith Urban is at a white piano. Nicole Kidman is standing right there next to him. They’re singing a song called "Female," and for a minute, the world of red carpets and Oscar trophies just disappears.
But here is the thing: that Keith Urban Nicole Kidman song isn't just a cute viral moment. It’s actually a pretty complicated piece of their history, especially now that the 2025 news cycle has turned their nearly 20-year marriage upside down.
Honestly, most people think they have a "duet" out there on Spotify. They don't. Not exactly. While Nicole’s voice is technically on the record, the story of how she ended up in the booth—and why Keith recently started changing the lyrics to his songs about her—is way more interesting than the tabloids let on.
The Secret Vocals on "Female"
Let’s get the facts straight first. When Keith released "Female" in late 2017, it was marketed as a solo track. It was a heavy song, written by Shane McAnally, Nicolle Galyon, and Ross Copperman in the immediate wake of the Harvey Weinstein allegations. It was meant to be an anthem.
Urban has always been vocal about being a "girl dad" to Sunday Rose and Faith Margaret. He wanted the song to feel like a "gospel soul prayer." To make it hit home, he did something subtle. He brought Nicole into the studio.
If you listen really closely to the chorus of the studio version—the part that goes "Sister, shoulder, daughter, lover"—you aren’t just hearing Keith. You’re hearing Nicole Kidman providing the "ethereal" background layers. She’s also joined by the songwriter Nicolle Galyon.

Nicole has famously said she has "no confidence" when it comes to singing, despite her Moulin Rouge days. She told Entertainment Tonight that she only sings for Keith. That’s it. So, getting her on a professional recording was basically a grand romantic gesture caught on tape.
That Viral Piano Video (The "Day of the Girl" Moment)
The reason everyone searches for the Keith Urban Nicole Kidman song is usually because of the 2018 video they posted for International Day of the Girl.
It wasn't a professional music video. Their daughters, Sunday and Faith, were actually the ones holding the camera. You can see Keith and Nicole harmonizing, and at the end, Nicole makes a little heart with her hands. It was the peak of their "couple goals" era.
Why "Female" Sparked Controversy
It wasn't all sunshine and heart emojis, though. The song actually took a lot of heat. Some critics called it "mansplaining" or felt it reduced women to a list of labels like "Virgin Mary" and "Scarlet Letter."
- The Criticism: Some felt a man shouldn't be the voice of a #MeToo anthem.
- The Defense: Urban argued it was a "pure celebration" of the women in his life.
- The Kidman Factor: Having Nicole on the track was seen by many as a stamp of approval that softened the blow of the critiques.
The Lyric Swap That Changed Everything in 2025
Fast forward to late 2025. The vibe changed. Suddenly, fans at Keith’s "High and Alive" tour noticed something weird during his performances of "The Fighter"—another song he famously wrote about Nicole.

The original lyrics are: "When they're tryna get to you, baby I'll be the fighter."
But in a video that went viral in September 2025, Keith looked at his guitarist, Maggie Baugh, and sang: "When they're tryna get to you, Maggie I'll be your guitar player."
Just days later, the news broke. Nicole had filed for divorce on September 30, citing irreconcilable differences. It felt like a gut punch to fans who had used their songs as the soundtrack to their own relationships. For years, Urban's setlist was a map of his marriage. "Once in a Lifetime" was about their engagement. "Got It Right This Time" was about their wedding.
Seeing him swap out those lyrics in real-time was like watching a live-action erasure of the "Nicole era" of his discography.
What Most People Get Wrong About Their Music
You’ll see a lot of "Top 10 Duets" lists online. Most of them are fake. Aside from the background vocals on "Female" and a few live encores—like the one in Las Vegas in February 2025 where she popped out for "But For The Grace of God"—they never actually released a formal single together.

Nicole was the muse, not the bandmate.
When Keith recorded "Gemini," he got into some hot water for the lyrics: "She’s a maniac in the bed, but a brainiac in her head." People thought it was TMI. Nicole, in her typical classy fashion, just laughed it off on the Kyle and Jackie O Show, saying she wasn't going to censor his art.
The Actionable Insight: How to Listen Now
If you’re looking for the "Nicole" influence in Keith's music, don't just look for her name. Look for the vulnerability.
- Listen to "Thank You" (2009): This is the rawest he ever got about her helping him through his sobriety early in their marriage.
- Watch the 2016 "The Fighter" Car Video: This is the most famous non-professional Keith Urban Nicole Kidman song moment. They’re just lip-syncing in a car, but it captures the chemistry that defined two decades of country music royalty.
- Check the 2025 Setlists: If you're heading to a show in 2026, keep your ears open. Urban is currently reworking his catalog. Many of the "Nicole songs" are being retired or updated with new lyrics, making the original recordings a time capsule of a relationship that, for a long time, seemed unbreakable.
The reality of celebrity "love songs" is that they’re rarely just about the person. They’re about the version of the person the artist needs at that moment. For Keith, Nicole was the "fighter," the "Gemini," and the "female" that defined his most successful years. Whether they're together or not, those tracks remain the most honest documentation of their 19-year run.
