So it only makes sense that at least one of his tattoos would shout out his soulmate.

“Babygirl” isn’t just the title of Kidman’s latest 2024 movie.

It’s also what Urban calls his wife as a nickname.

“Keith’s not allowed to call anyone else Babygirl,” she added.

“But now, because of the film, it’s taken on a different meaning.

So he’s like, ‘No, I still have total rights over Babygirl!'”

It’s understandable why Kidman is so possessive over the nickname.

The “Batman Forever” star was instantly attracted to Urbanwhen they first met in 2005.

They married in 2006, and both have enjoyed 18 long years together since.

After so much time spent building their family, babygirl is a nickname that Kidman earned the rights to.

Years ago, Urban used to have the words Omnia Vincit Amor written on his right wrist.

But tattoos aren’t the only way Urban has creatively expressed his love for Kidman.

“I don’t censor his art.

If I can be a muse for it,” she said in an interview withKIIS.

However, she admitted that she’s not always thrilled with being referenced in his songs.
