Nicole Kidman cheers Knicks fans in spirit after missing Game 4

On Thursday (June 11), Nicole Kidman didn’t make it to the Knicks’ bonkers Game 4 of the NBA finals, but she still made sure her fandom showed up loud. In an Instagram Story, the Margo's Got Money Troubles star gave her enthusiastic thumbs-up to Taylor Swift, Este Haim, and Alana Haim, telling the trio she was “Right there with you girls!” over a video of Swift shouting and pointing to her shirt.

That matters because it ties a huge live sports moment to celebrity amplification in near real time. Game 4 on Wednesday night (June 10) was the one where the Knicks came back from a 29-point deficit to win as time expired, then took a 3-1 lead in the series. Kidman’s support did not show up on the arena floor. It showed up in the feeds, where everyone else watching already was.

So what did the Haim sisters do to earn headlines almost as fast as the comeback? They wore custom name-pun Knicks tees that turned celebrity culture into basketball merch. Este and Alana, part of the band Haim, were representing with custom T-shirts built around Knicks wordplay. The specific shirt that got screen time included “Knickole Kidman” and “Stevie Knicks,” with the video showing Swift hyping Este’s Kidman-coded top before the camera turns.

Kidman also reposted the celebration clip, and in both the Story and the repost, the vibe was clear: this was fun-first fandom, not just publicity. The repost came with Kidman’s caption “My girls!” and the line “I just wanna have fun!” The trio even danced to Cyndy Lauper’s 1983 Billboard Hot 100 No. 2 hit “Girls Just Want to Have Fun.” It is a small thing, but in modern media it is also a business model. A live event becomes a content engine, and these creators are feeding it with a format fans immediately understand: a repeatable, photo-friendly meme.

What makes it more interesting for operators and boards is the DIY supply chain behind the look. Vogue spoke with Alana Haim after the game, and the practical details are the story’s hidden backbone. Alana said she bought the royal blue shirts from Michael's for $2.99 each and screen-printed them herself after getting a text from Swift that read, “I want to wear this shirt to the game, can you make it for me?” That question sounds small, but it is basically a demand signal from one of the biggest pop stars on the planet. Swift’s ask accelerated the timeline and added urgency, then turned into an on-the-fly design workshop.

The design process became part of the content. Haim said she thought her pal would never ask, then they talked about fonts and sizing. Swift also offered up her idea for a music-related Knicks pun, setting off a parade of punny ideas. The goal, Alana explained, was not scale or royalties. “We really just wanted to have fun,” she said, and they wanted to make people laugh, so they put the ideas on shirts and decided to wear them.

And then the remix kept expanding. For the record, Mariska Hargitay also joined in, wearing a “Stevie Knicks” shirt, reportedly sitting with the group and ending up in countless clips from the game. Este brought an extra shirt “because she always does,” according to the account, which is how Hargitay ended up involved. That is how celebrity merch travels now. It is less about official channels and more about social distribution: one extra piece gets into the right group, and suddenly it is everywhere. The same logic likely applies to the rumored third shirt: Danielle Haim, the lead guitarist and singer, was also reportedly at the game wearing a shirt reading “Knickolas Cage,” though she did not sit with her siblings on celebrity row.

Finally, the timeline matters. Game five is scheduled for Saturday (June 13) in San Antonio. If the Knicks win it, that would mark the team’s first championship in 53 years. In other words, this content wave is not a one-off. It is attached to a high-stakes endgame, which means more eyes, more cameras, and more incentives for everyone involved, from athletes to fans to brands, to show up with something that looks good on replay.

For executives watching this ecosystem, the second-order lesson is not that a pun shirt wins a title. It is that live culture and creator-made merchandising can turn a single broadcast moment into a multi-day, multi-platform narrative. Celebrity endorsement here is not a press release. It is a repost. A “Right there with you girls!” message. A video that gets clipped, captioned, and re-shared alongside the actual scoreboard chaos. In a world where attention is the scarcest resource, this is a case study in how to convert a real-time sports spike into durable, shareable identity. And if you are building a media, brand, or product strategy, that is the part worth stealing.
