AceShowbiz - Country star Keith Urban helped his wife Nicole Kidman ring in her 51st birthday by leading a crowd serenade at his concert in Wisconsin on Tuesday night, June 19.
The Oscar winner turned another year older on Wednesday, and Keith helped to kick off celebrations on a high note a few hours early by calling on fans at the Country USA Festival in Oshkosh to join him in a rendition of Happy Birthday.
Keith also asked the audience to refer to Nicole as "baby girl", and he filmed the sweet gesture on his phone.
The actress, who is working on the second season of her critically-acclaimed TV drama Big Little Lies in California, later posted the footage on Instagram, and gushed about the special surprise.
"What a gift - my husband and everyone at @officialcusa Oshkosh WI singing me Happy Birthday!!!!!!" she captioned the video.
Nicole's close pal and Big Little Lies co-star Reese Witherspoon also wished the birthday girl well on social media, as she shared a snap of the ladies hanging out together.
"Happy Birthday to this remarkable woman who I’m lucky enough to work with and call my friend," Reese wrote. "Everyday with you is an inspiration! Keep shining bright, Nic!!".
