Keith Urban posted a public birthday message to his ex-wife, Nicole Kidman, on Instagram on June 20, 2026 [1].

The interaction provides a rare glimpse into the relationship between the former couple following their high-profile separation. Public displays of affection or friendship after a divorce often signal to the public and industry peers that the split was amicable.

Urban used Instagram Stories to wish Kidman a happy birthday as she turned 59 [1]. He wrote, "Happy birthday Nicole Mary" [2]. The 58-year-old singer used multiple punctuation marks in the post to mark the occasion [3].

Kidman responded to the gesture by sharing a sunny photograph of herself. In the caption for the image, she wrote, "Another trip around the sun" [4].

This exchange occurred approximately six months after the couple's divorce was finalized in January 2026 [5]. The timeline suggests a transition toward a friendly co-parenting or platonic relationship after the legal dissolution of their marriage [5].

While the couple has maintained a level of privacy since their split, the public nature of these posts acknowledges the continued bond between the two artists. Urban's message specifically addressed Kidman by her full name, Nicole Mary, in the social media tribute [2].
