The star accessorised with sheer elbow-length gloves and pulled her hair back into a low ponytail and went for natural makeup, but with a smokey eye.

It appears as though Nicole's husband Keith Urban was not at the event, but the star was in Las Vegas supporting the country singer late last month.

Nicole shared a snap from the concert of herself looking at the stage as confetti fell from above, with the star describing it as a 'magical night'.

The pair celebrated their 17th anniversary the day before, with Nicole sharing a sweet snap of the pair embracing.

"Happy Anniversary my Love," she wrote alongside the black and white snap.

"Faves," Vanessa Hudgens commented on the photo.

“The best,” one person added, with another writing: “What a lovely photo”.

Nicole and Keith first met in 2005 at the G'day Australia event in Los Angeles, with the pair marrying just one year later.

"Meeting her and getting married wasn't life-changing, it was life-beginning," Keith told CBS Sunday Morning in 2016. "It was literally, like, 'Okay, life starts.'"
