The fairy-tale romance that once had the entire K-pop world buzzing may be crashing down in spectacular fashion. Frédéric Arnault, the dashing CEO of TAG Heuer and heir to the LVMH luxury empire, is at the center of explosive new rumors claiming he has quietly rekindled an old flame with his German ex-girlfriend while Lisa from BLACKPINK is left picking up the pieces.

For nearly three years, the pairing of the global superstar and the French billionaire heir seemed like a match made in luxury heaven. Their relationship first exploded into the spotlight in July 2023 when sharp-eyed fans spotted them sharing an intimate dinner in France, with Lisa resting her head affectionately on Frédéric’s shoulder. From private jets to romantic getaways across Europe and Asia, the couple was frequently photographed looking blissfully in love. Insiders claimed they had even met each other’s families, sparking whispers of engagement rings and a future wedding that would blend K-pop royalty with old-money European power.

But behind the glamorous facade, cracks appear to have been forming. Sources close to the couple say the once-constant public displays of affection have vanished. Lisa was last seen jetting between continents for her solo activities and BLACKPINK commitments, while Frédéric’s schedule kept him firmly planted in Paris and luxury industry events. The final blow came when eagle-eyed netizens noticed Frédéric liking several Instagram posts from Caroline Daur — his strikingly beautiful German ex — including cozy group photos that showed them looking far too comfortable together.

Caroline Daur, a 31-year-old self-made fashion powerhouse, is no ordinary ex. The blonde influencer launched her blog Carodaur.com in the early 2010s and skyrocketed to fame with over 4.6 million Instagram followers. Named to Forbes’ 30 Under 30 in 2019, she has walked for Dolce & Gabbana, graced Vogue Japan’s cover, and even landed acting roles in Netflix productions. Known for her independent spirit, Caroline has repeatedly stated she handles her entire career without agents or assistants. Old rumors from 2023 already linked her romantically with Frédéric, including sightings of the pair dining in London and working out together in New York.

Now, fresh photos and social media activity have fans convinced history is repeating itself. Reports claim Frédéric was seen spending time with Caroline in private European settings just weeks after Valentine’s Day 2026 passed without any public gesture from him toward Lisa. Lisa herself posted solo content wishing fans a happy Valentine’s, noticeably avoiding any mention of romance — a detail that sent BLINKs into a frenzy of speculation.

Investigators digging into the timeline point out that Frédéric and Caroline’s connection may never have fully ended. Whispers suggest the German model remained in his orbit even after he went public with Lisa, with occasional “friendly” meetings that have now escalated. One source told European tabloids that the chemistry between Frédéric and Caroline was undeniable from the moment they reconnected at a high-society event, leaving little room for doubt about where his heart truly lies.

The timing could not be more painful for Lisa. The Thai-born superstar has been riding high with solo success, fashion campaigns, and international appearances, yet her personal life now faces intense scrutiny. Fans who once celebrated the couple’s jet-set romance are now divided — some rushing to defend Lisa as a strong, independent woman who doesn’t need a billionaire by her side, while others mourn the apparent end of what looked like a modern-day princess story.

Frédéric, for his part, has remained largely silent on the matter, choosing instead to focus on his duties within the LVMH empire. His family, one of the wealthiest in Europe, has always kept personal matters tightly under wraps. Whether the Arnault clan ever fully accepted Lisa remains a topic of heated debate among fans.

As of now, neither Lisa nor Frédéric has issued an official statement confirming a breakup. However, the sudden radio silence, combined with the resurfaced photos and lingering likes on Caroline’s posts, has created a perfect storm of heartbreak rumors that shows no sign of slowing down.

Is this the quiet, dignified end of one of K-pop’s most talked-about romances? Or is there still a chance for reconciliation before the final curtain falls? One thing is certain — the world is watching every move, every like, and every private jet flight with breathless anticipation.
