Nicole Kidman and Keith Urban's love story spans more than 15 years, but the two never stop expressing their appreciation for each other.

Marking five years of his studio album Graffiti U, Keith shared a romantic throwback video of himself and his wife on stage. In it, the Roar star is perched on a stool and gazing adoringly up at Keith as he sings "Parallel Line" — produced with famous ballad singer and songwriter Ed Sheeran.

An intimate crowd cheered on as the country singer strummed on his guitar and the Australian actress coyly sang along.

At the end of the clip, Keith moved the microphone closer so they could sing together. The two crooned: "Baby, be mine now. Maybe it's time we put our hearts in a parallel line. Take a little bit of my heart tonight. No, I literally don't mind." You can see Nicole is clearly smitten by the gesture.

Fans of the couple couldn't hide their admiration for the public display. "I love that he made sure the mic was right in front of her," one person wrote under his TikTok. "What a beautiful love story you both have," another added. "Relationship goals!" a different user said.

Fortunately for those folks, neither Keith nor Nicole shy away from posting about one another on social media. The two showed they never go out of style, as evidenced by his TikTok below at Taylor Swift's Eras Tour. Both danced along as she performed onstage.

The Brown Eyes Baby singer shared his pride for Taylor, who he recorded the duet "That's When (Taylor's Version)" with on her Fearless re-recording. "Big <3 from all of us," he wrote as a screen caption.

In 2015, Keith was a surprise guest performer during Taylor's 1989 World Tour where they sang his songs, “John Cougar, John Deere, John 3:16” and “Somebody Like You.”

Fingers crossed we see more of the couple on the road again!
