In the world of celebrity influence, few trends travel as swiftly—or as far—as those set by global stars. This week, two distinct but interconnected stories have captured the attention of fans and industry watchers alike: the meteoric rise of Black celebrities and other diverse icons as brand ambassadors in the luxury fashion and beauty world, and the headline-making dietary choices of Jung Kook, the youngest member of BTS, who has adopted the One Meal A Day (OMAD) diet. Each story, in its own way, reflects how celebrity choices ripple outward, shaping conversations on representation, health, and culture across continents.
Let’s start with the world of high fashion, where the landscape of brand ambassadorship has shifted dramatically in recent years. According to a recent roundup published on February 16, 2026, by Business of Fashion, the last five years have seen a remarkable diversification in the faces representing luxury brands. Black celebrities, in particular, have not only become the faces of some of fashion’s most recognizable houses but are also actively reshaping the global conversation around representation and inclusion.
From the red carpets of Hollywood to the ateliers of Paris, a new generation of stars is making its mark. American actress and Golden Globes nominee Chase Infiniti, celebrated for her role in "One Battle After Another," has been named the latest house ambassador for Louis Vuitton under Nicolas Ghesquière’s creative direction. Canadian actress Taylor Russell, known for "Bones and All," has joined Dior’s ambassador lineup just as Jonathan Anderson prepares for his debut couture collection at the iconic house. Not to be outdone, Australian actress Sophie Wilde, famous for her role in the supernatural horror film "Talk to Me," made her debut as a Dior ambassador with the Rose des Vents jewelry collection.
The influence extends well beyond actresses. Actor and musician Lakeith Smith, star of "Die My Love," has become a regular face for Dior’s menswear collections, while A$AP Rocky, already a formidable force in fashion, launched his own luxury jewelry brand, Pavē Niteō. His appointment as Ray-Ban’s first creative director in 2025—and as a global ambassador for Gucci in 2023—underscores his boundary-pushing role in the industry. British-Nigerian actor Damson Idris, fresh from his breakout role in "F1: The Movie," joined Prada’s ambassador roster and fronts his own fine jewelry line, Didris.
Women, too, are continuing to break new ground. In 2025, actress Nia Long was named Estée Lauder’s brand ambassador for North America, joining a storied roster that stretches back eight decades. Ayo Edebiri, star of HBO’s "The Bear," became the first brand ambassador for Chanel under Matthieu Blazy, debuting several of his collections on the red carpet. Pulitzer Prize-winning rapper Kendrick Lamar was appointed global ambassador for Chanel eyewear, a partnership that began in 2023 and was cemented when Lamar became the most Grammy-awarded hip-hop artist in history, accepting his award in a custom Chanel tuxedo and eyewear.
Other notable appointments include Michael B. Jordan for David Yurman, rapper Future for Louis Vuitton under Pharrell Williams’ creative direction, and Rihanna, who made history as Dior’s first Black ambassador in 2015 and succeeded Charlize Theron as the face of Dior’s J’adore fragrance in 2024. Supermodel Naomi Campbell now represents Boss watches and jewelry, while Zoe Kravitz became the first ambassador for British jeweler Jessica McCormack and continues her collaboration with Omega watches.
Icons like Diana Ross, who fronts Saint Laurent’s 2024 campaign, and Zendaya, the face of Louis Vuitton’s 130th anniversary campaign, demonstrate how heritage brands are turning to diverse, multigenerational stars to connect with new audiences. Zendaya’s ambassadorships with Rolex, Bulgari, and Lancôme Beauty further cement her status as a cross-industry powerhouse.
But it’s not only the world of fashion and beauty that’s feeling the impact of celebrity influence. On the same day, NDTV reported that Jung Kook, the youngest member of the K-pop sensation BTS, revealed his adoption of the OMAD diet—a regimen where one consumes all daily calories in a single meal, fasting for the remaining 23 hours. The news comes just as BTS prepares for its highly anticipated comeback in March 2026, and it has sparked widespread debate, especially among young fans in India and beyond who look to K-pop idols as lifestyle trendsetters.
Jung Kook’s approach is not without precedent; celebrities such as Shah Rukh Khan, Channing Tatum, and Bruce Springsteen have also reportedly tried the OMAD diet. However, experts warn that while OMAD may offer benefits like weight loss, improved fat metabolism, and better insulin sensitivity—as noted in studies published in Frontiers in Physiology—the diet is not universally sustainable or safe. The Korean Medical Association recommends 2,100-2,400 kcal/day for an average Korean man, while Indian guidelines suggest 3,000 kcal/day for men with high-intensity lifestyles. For Jung Kook, whose regimen is medically supervised and shaped by 18 months of military service, the discipline and structure required are significant.
But for the broader public—especially young Indians influenced by the K-wave—the risks can outweigh the rewards. The Indian Council of Medical Research and the National Institute of Nutrition emphasize that the Indian diet should be balanced and spread over multiple meals to maintain adequate nutrition. OMAD, experts warn, can lead to nutrient deficiencies, gastric issues, and is particularly unsustainable for teenagers and young adults with high activity levels. "Without consistent medical supervision, OMAD can be harmful, as the long-term side effects on health can lead to serious ailments," NDTV cautions.
As the popularity of K-pop and global fashion icons continues to grow, so too does the responsibility of fans and consumers to approach celebrity-endorsed trends with caution. The allure of following in the footsteps of stars like Jung Kook or Zendaya is powerful, but experts and industry leaders alike urge individuals to prioritize scientifically backed guidelines and personal health needs over fleeting trends.
In the end, whether it’s a new face on a luxury campaign or a bold approach to diet and fitness, the choices of celebrities reverberate far beyond the worlds they inhabit. Their influence shapes not just what we wear or eat, but how we see ourselves—and each other—in an increasingly interconnected world.
