Australia’s very own Nicole Kidman has been treated to a rendition of Happy Birthday by her country rocker husband Keith Urban and his fans during a show at a country music festival in the United States.

The ‘Big Little Lies’ star turned 51 on Wednesday and has posted a clip of her husband and the crowd at the Country USA Festival serenading her on Instagram.

“What a gift – my husband and everyone at @officialcusa Oshkosh WI singing me Happy Birthday!!!!!!” Kidman wrote.

At the end of the song Urban turns to the camera and says: “I love you baby. Happy Birthday!”

Kidman and Urban, 50, have been married since 2006 and have two daughters together.
