To celebrate, the country star surprised a Nashville crowd Monday night with an appearance by his wife, Nicole Kidman. The couple performed a duet together of Urban's latest track, "Parallel Line."
Urban first introduced "Parallel Line" back in January as the second single to be featured on Graffiti U. If you're wondering why the lyrics are pulling at your heartstrings to the extreme, it's because master crooner Ed Sheeran co-wrote the new tune.
Keith Urban's 2018 Graffiti U World Tour kicks off in June with special guest Kelsea Ballerini.
