Keith Urban plans to celebrate his daughter Sunday Rose's 18th birthday in a private lunch with her and her younger sister, Faith Margaret, before heading to Minnesota for a performance. Ex-wife Nicole Kidman is not expected to attend this family gathering, according to a report by New Idea.

An insider told the publication that while it remains "too raw" for Kidman and Urban to share a table, Urban has been invited to a larger birthday party later that day. This arrangement allows Urban to celebrate with Sunday and Faith separately before his commitment at the Lakefront Music Fest. The reported plans come after the couple finalized their divorce in January, following a separation last summer after 19 years of marriage.

Despite celebrating separately, the former couple are reportedly focused on a united co-parenting approach for their daughters. The birthday marks a significant moment for Urban, who has maintained a low profile with his daughters since the split was announced last September.

In parallel, Nicole Kidman shared a public tribute to Sunday on Instagram, posting a series of family photographs with the caption: "Happy Birthday our beautiful Sunday Rose. We love you so much." The post included childhood photos of Sunday, one in Kidman's arms and another in an angel costume.

Sunday Rose has been stepping into the public eye, having launched a modeling career at age 16. Despite some initial online criticism regarding her runway walk, she has continued to pursue a career in fashion. She recently walked for Dior during Paris Fashion Week. This past Monday, she participated in the Dior show in Paris, and the following day, she reached her legal majority. Kidman's Big Little Lies co-star Reese Witherspoon also extended birthday wishes in the Instagram comments.
