Nicole Kidman’s Daughter Stuns in Prom Gown—But One Detail Has Everyone Divided

All eyes are currently on Sunday Rose Kidman Urban—and it isn’t solely because of her high school prom.

On April 19, 2026, the 17-year-old daughter of Nicole Kidman and Keith Urban shared a simple Instagram update with a brief caption: “prom <3.”

Yet, the photo rapidly gained viral attention, primarily due to her stunning dress—and its staggering price tag.

It is easy to assume that the last several months have been incredibly turbulent for the Kidman-Urban family. For Nicole Kidman and Keith Urban, 2025 marked a massive turning point following nearly two decades of marriage.

The famous pair quietly separated early in the summer and began residing apart, officially finalizing their divorce this past January with Kidman citing “irreconcilable differences.”

Ever since the split, rumors have escalated concerning how much time Keith Urban actually spends with his kids. Sources suggest that their custody arrangement grants Kidman the bulk of the year with their daughters, leaving Urban with a much more restricted schedule.

During an interview in March 2026, 17-year-old Sunday Rose Kidman Urban openly praised her mother’s profound influence—but noticeably left her father out of the conversation.

“My mum is someone who has always been incredibly creative and my greatest inspiration in life. She plays a crucial role in everything I do,” Sunday stated.

These recent developments have fueled further gossip about possible inner-family turmoil. A couple of months after the separation, Sunday purportedly unfollowed her dad on Instagram, following in her mother’s footsteps—even though Urban is reportedly still following her account.

Furthermore, rumors point to a strained relationship between Urban and both of his daughters, including younger sister Faith Margaret, following the divorce. Speculation has even surfaced that Sunday rejected the idea of meeting Urban’s alleged new partner, adding to the widening rift.

Meanwhile, Sunday Rose Kidman Urban is stepping further into the public eye—from high-profile fashion events to viral internet sensations like her prom look. Therefore, while the household navigates profound private shifts, they are simultaneously transitioning into a fresh era in the spotlight.

For the big evening, Sunday wore a strapless, vintage Oscar de la Renta gown from their Spring 2022 collection. The piece featured a glittering silver bodice crafted to look like delicate strawberry vines, flowing gracefully into a voluminous white tulle skirt. It was elegant, eye-catching—and incredibly expensive. A comparable edition of the garment supposedly fetched around $5,800 on resale platforms, marked down from an initial retail cost of almost $13,000.

And keep in mind—this was simply a school prom.

Predictably, the internet was full of opinions. While some were absolutely captivated by the ensemble, calling her “beautiful” and “divine,” others debated if such a lavish dress was appropriate for a standard school event.

Detractors labeled it “way over the top” and “unnecessary,” with one commenter flatly declaring, “It’s not the red carpet.”

Some observers focused less on the outfit and more on her physical appearance, noting her strong resemblance to her dad. Comments like “She’s a mini Keith” swiftly spread across social platforms.

Conversely, fans defended the viral moment—highlighting her upbringing and the reality that her parents have the financial means to easily afford it. A few supporters pointed out that Sunday is already establishing herself in the fashion industry, which makes the extravagant look feel fitting rather than excessive.

This viral prom sensation coincides with a thrilling period for the family. Nicole Kidman recently revealed that Sunday will be her date for the Met Gala on May 4, signaling a major mother-daughter outing at one of fashion’s most prestigious events.

Between a prom dress that dominated the news cycle and a Met Gala debut just around the corner, it is obvious that Sunday Rose is experiencing a banner year.

As she begins to carve out her own space in the limelight, Sunday also shared a crucial piece of guidance she received from her mom:

“The most significant piece of advice my mom has given me about the industry is to always be punctual,” she noted.

“There will always be occasions with an early start that you might not feel like waking up for, but being on time is crucial as it demonstrates your readiness and appreciation for being present.”
