There is a version of this story in which a brand pays a global celebrity millions of dollars to be photographed using its product. That version requires contracts, NDAs, exclusivity clauses, and a creative brief. Lime’s version requires none of those things. It requires a traffic jam, a bike rack, and a paparazzo in the right place.
The Kim and Lewis Chapter
In September 2026, Kim Kardashian was in London for the opening of Skims’ first international flagship store on Regent Street. Lewis Hamilton was with her. Both were photographed cycling Lime bikes through central London with friends.
The combined estimated net worth of the two people on those Lime bikes was $2.5 billion. Kardashian owns SKIMS, valued at $5 billion in a 2025 funding round, and has built one of the most commercially successful celebrity brand portfolios in modern history. Hamilton earns $60 million per year racing for Ferrari and has been estimated to have generated over $880 million across his Formula One career. Both of them chose to spend an afternoon on a £3-per-ride hire bike.
Hamilton was photographed shooing away a paparazzo who had spotted them. Kardashian appeared relaxed. Neither had been contracted to be there. Neither was paid.
The images spread immediately across entertainment press, sports media, and marketing publications. A brand whose core product costs a few pounds to rent had been endorsed, without a contract or a briefing or a deliverable, by two of the most commercially powerful individuals on earth, in the middle of one of the world’s most photographed cities.
The Competitor Who Noticed
What turned the story from a celebrity news item into a marketing conversation was Forest, a rival dockless e-bike company that operates across 19 London boroughs. Forest posted on social media: “We have a bone to pick with you!” directed at Kardashian, noting that its own bikes were equally available across the capital.
Forest began as an idea in a London pub garden in 2019. Its entire brand identity is built around being locally rooted rather than globally scaled. By turning Kardashian’s Lime ride into a playful competitive exchange, Forest extracted its own earned media moment from someone else’s celebrity endorsement, reminding London that the two companies compete for the same riders and that Kardashian’s choice had been one brand’s gain at another’s expense.
The Chalamet Moment
The Kim and Lewis chapter was not Lime’s first major unpaid celebrity endorsement in London. In January 2025, Timothée Chalamet arrived at the London premiere of A Complete Unknown, his Bob Dylan biopic, at BFI Southbank. He did not arrive in a limousine. He did not arrive in a blacked-out SUV. He arrived on a Lime electric bike, dirt near the pedals, phone out, smizing briefly for the cameras before dismounting, ending his ride on the app, and walking into the premiere as though nothing unusual had just happened.
Chalamet later explained himself on the French television programme Quotidien. There had been a traffic jam. He had decided to beat it by hiring a bike. “It’s ecological,” he said. The decision had not been planned. Lime confirmed through a spokesperson to PRWeek that the arrival was entirely organic. The brand had not been involved.
The aftermath produced one more chapter. Chalamet had parked the bike in a non-designated area. He told Quotidien he had received a fine of approximately £65. The Guardian contacted the local council, which said it had not issued the fine, and Lime confirmed their own in-app penalty would have been £2. The actual amount was disputed. The story was not. Lime’s global communications director Russell Murphy posted on LinkedIn that the brand appreciated becoming the “preferred red carpet accessory for the biggest movie star on the planet.”
Lime’s chief brand and communications officer Carolyn Chiang Rosebrough described what the moment had captured: Chalamet was the “perfect embodiment” of Lime’s sustainability goals, and the brand welcomed the association precisely because it had arrived without engineering.
The Broader Pattern
Chalamet and the Kardashian-Hamilton pairing are not isolated incidents. Harry Styles has been photographed on Lime bikes in London. Paul Mescal has been pictured on them. Olivia Rodrigo celebrated her Grammy nomination with a breakfast-time bike ride on one. None of these was paid arrangements.
Lime’s chief brand officer described the accumulation of organic celebrity moments without mystifying it: “It’s not magic.” The brand’s product is affordable, widely available across multiple cities, genuinely useful for short urban journeys, and operates in a cultural moment when sustainability has become a visible personal value among the celebrities using it. When famous people use things that actually work, in public, in cities full of photographers, the cameras follow.
What This Tells You About Earned Media
There is a documented gap between what paid endorsements produce and what organic celebrity usage produces, and it runs in a consistent direction. A paid post signals commerce. An organic photograph signals authenticity. The audience’s ability to identify which is which has increased significantly in the social media era. A celebrity who chooses something for themselves, at their own cost, in a situation without a photographer arranged in advance, carries more persuasive weight than a celebrity who chose it because a brand paid them to.
Lime did not plan Chalamet’s red carpet arrival. It did not arrange for Kardashian and Hamilton to be photographed outside Skims’ flagship store. It did not brief any of the actors, musicians, or athletes who have been seen on its bikes across London, New York, or Paris. It built a product that is genuinely useful in exactly the situations where famous people also need to get somewhere quickly and cheaply without being stuck in traffic.
The product did the work. The cameras did the distribution. Lime did not need to be in the room.
