Reese Witherspoon, who starred in and executive produced HBO's Big Little Lies alongside Kidman, also wished her close pal a happy birthday on social media.

Along with commenting on Urban's post, "Happy Birthday Nic!! 💖," Witherspoon, 44, posted her own birthday tribute to Kidman on Instagram, sharing three photos of the pair together.

"Happy Birthday to my dear friend, my fierce creative partner, my Australian sister!! @nicolekidman, I’m so lucky to have you in my life...learning and laughing with you! I’m celebrating YOU today!! ✨💕🎂," she wrote.

Recently, Kidman has been on the mend after she broke her ankle while going on a run. Last month, the actress thanked her fans for their "well wishes."

"Thank you for all the well wishes and love ❤️," she wrote on Instagram alongside a selfie of her and Urban. "I’m back on the right track… and almost back on the right foot 😉."

News of Kidman's injury was first made known by Urban when he appeared on the Australian show The Project last month.

"She broke her ankle so there’s not been a whole lot of dancing in the house," the country star said. "About five weeks ago, she was running around the neighborhood as she does and just didn’t see a pothole and rolled her ankle and got a small break in her ankle."

"She's been relegated to the boot for the last handful of weeks and is still getting through it," Urban added. "But her spirits have been amazing, I gotta say. She’s been handling it way better than I would’ve."
