Keith Urban's wife, Nicole Kidman, paid the country singer tribute for his 49th birthday on Oct. 26, sharing two adorable photos on Facebook with equally heartwarming captions.

One features Urban in full dad mode, with one daughter hanging off his back and the other hugging him as they horse around outside in sweet, frilly dresses. The other is a photo of Urban and Kidman living it up in a photo booth, posed t in front of a glittering background, with Urban in star-shaped sunglasses and Kidman in a shimmering top hat, clearly having the time of their lives together.

But it's the captions which speak volumes about how much Urban is adored by his family, both his daughters and his wife.

"Happy birthday to the most loving husband, father and friend we could ever ask for,” Kidman writes under the photo of the couple, before revealing a couple of quirky nicknames: "We love you Big Cat Daddy. Love, Little Miss Honky Tonk."

"You are so loved Keith Lionel. Happy birthday. Love from your girls, Sunnie, Faith & Nicole Mary xxx,” the other says.

Urban and Kidman have been married for 10 years, and the Aussies have said their relationship is solid because it’s based on a foundation of friendship.

“You know, she’s my best friend. I’ve never had anybody on the planet that knows me as well as she does,” Urban tells People about Kidman. “I would love to have been worthy of somebody like Nic, but I was a long way from it when we met, but somehow we just found there was love there, real love. I literally just feel like the luckiest guy on the planet.”

Urban also posted a super cute photo with Kidman on his birthday, noting it was his best one yet.

The singer has been on his Ripcord Tour with Maren Morris and Brett Eldredge, and it was recently announced that he will perform New Year’s Eve in Nashville. He’s gearing up to perform on the 2016 CMA Awards, where he's nominated for Entertainer of the Year, Male Vocalist of the Year, Album of the Year and Musical Event of the Year.
