Nicole Kidman may be married to one of the most famous country singers on the planet, but even Keith Urban's famous wife isn't an expert when it comes to hilarious lines from country songs (or not).

Kidman stopped by 'The Ellen Show' on Thursday (Oct. 30) to talk with host Ellen Degeneres about life with the country star and her newest film, 'Before I Go to Sleep.' The two covered a wide range of topics -- everything from the love letters that she and Urban write to each other every day they are apart to how the 'Somewhere in My Car' singer "literally carried" her after the sudden death of her father.

But given her close relation to one of the most well-known names in the industry, DeGeneres couldn't let Kidman get away without testing her knowledge of country music! During the 'Country Song or Country Wrong?' game, Kidman and the comedienne had fun guessing if the song names on the screen actually were real songs.

"I better win this!" said the actress with a laugh, knowing her reputation as the wife of country's beloved Aussie was on the line. But with ridiculous titles like 'Her Teeth Were Stained, But Her Heart Was Pure' and 'She Got the Gold Mine and I Got the Shaft,' we're just impressed that she got two out four guesses correct!

Believe it or not, both of those titles actually are country songs! The one that wasn't? 'Don't Cry on My Shoulders 'Cause You're Rustin My Spurs.' Well, that might just be a big hit soon enough.
