On Saturday night, October 26, the Luke Combs and Eric Church-led Concert for Carolina was held to raise money for Hurricane Helene victims.

With a star-studded lineup that included James Taylor, Sheryl Crow, Bailey Zimmerman and many others, fans were expecting an unforgettable night full of one-of-a-kind performances and special surprises. But Church and Nicole Kidman leading the crowd in a rendition of “Happy Birthday” probably wasn’t on anyone’s bingo card.

However, that’s exactly what happened when Kidman hopped onstage at the sold-out stadium event to join her country superstar husband, Keith Urban, who was one of the headliners of the night.

Kidman shared how proud she and Urban were there to be in Charlotte, N.C. for the event, which she says became a possibility “because of Eric giving Keith a call.” But she also wanted to briefly put the spotlight on her husband, who was celebrating his 57th birthday on Saturday.

“I do wanna say, it’s his birthday tonight and he went, ‘The one thing I can do….’” Kidman told the crowd during her brief time onstage, explaining that Urban was excited to spend his special day taking part in the benefit.

Before she left the spotlight, Kidman and Urban brought Church up onstage, and the Chief led the crowd in singing “Happy Birthday” to Urban, who looked a little sheepish at the attention, but clearly enjoyed the fun, spontaneous moment.

Church stayed onstage for a duet with Urban after the birthday festivities. The two performed their 2013 duet “Raise ‘Em Up.”

The Concert for Carolina began after Combs, a North Carolina native, vowed to do something to help those in his home state impacted by the devastating storm. The show sold out Charlotte’s Bank of America Stadium, and it was also available to livestream on Veeps.

The proceeds from the Concert for Carolina will be split between Combs and Church’s Chief Cares Foundation. Combs will send his portion to Samaritan’s Purse, Manna Food Bank, Second Harvest Food Bank of Northwest NC and Eblen Charities.
