A recent Keith Urban performance has surfaced following his split from Nicole Kidman.

As fans speculate about what may have happened between the two, Urban, 57, caught more attention recently after he changed the lyrics to his song “The Fighter,” featuring Carrie Underwood, during a recent performance.

As seen in a clip from the performance shared on Instagram by Urban’s utility player and rising country star, Maggie Baugh, a lyric from the song was changed to include her name as the two performed together.

The original line “When they’re tryna get to you, baby I’ll be the fighter” was sung as “When they’re tryna get to you, Maggie I’ll be your guitar player” by Urban. Baugh, 25, added two emojis over the video: “🫣 🤯.”

“Did he just say that👀,” she captioned the clip. Baugh shared the footage on Saturday, Sept. 26, before news of Urban and Kidman’s split.

PEOPLE has reached out to reps for Urban and Baugh for comment.

PEOPLE confirmed Urban and Kidman’s separation after 19 years of marriage on Monday, Sept. 29. According to documents obtained by PEOPLE, on Tuesday, Sept. 30, Kidman, 58, filed for divorce from the country star in Nashville, where the couple has lived since 2007, listing their date of separation as the date of filing, and citing irreconcilable differences as the reason for the split.

Urban and Baugh were on tour this summer for his High and Alive World Tour, and have more shows scheduled through mid-October. He also has concerts scheduled for the Bahamas and the U.K. in March 2026.

The song, which is off Urban’s ninth studio album Ripcord, was inspired by the early days of Urban’s romance with Kidman.

“It’s all from a conversation my wife and I had early on in our relationship, that when things get tough, I need to hold her tighter and just try to take care of her,” Urban told Billboard in 2017.

“The song is about wanting to heal somebody, wanting to take care of somebody, wanting to protect somebody. It’s really like a vow in so many ways,” he continued, referring to Kidman as “female and tender.”

“I want that tenderness to not have to get hardened to the world,” said Urban. “That’s my job as her husband, to put myself around her so she can remain that way. And that’s really the chorus of The Fighter.“

Urban told the outlet that the song came into fruition while he and Kidman spent time in London, as she starred in the West End production of Photograph 51 during the fall of 2015.

A source in Urban’s circle told PEOPLE Tuesday that the country star has “just been going through some stuff” as of late.

“He has been making questionable choices for some time now and this was not the case of them just drifting apart,” added a Kidman source.

Kidman and Urban tied the knot in June 2006 and share two children together — daughters, Sunday Rose, 17, and Faith Margaret, 14. Kidman is also a mom to Bella, 32, and Connor, 30, with ex-husband Tom Cruise.
