Dua Lipa and Callum Turner: $1.73 million

Setting the structural tone for modern celebrity matrimony, pop sensation Dua Lipa and actor Callum Turner masterfully blended quiet legality with high-octane luxury across two countries. The couple officially tied the knot during an intimate civil ceremony on May 31, 2026, at London's Old Marylebone Town Hall, where the venue cost under $1,000, but the wardrobe exceeded $600,000 - thanks to a custom Schiaparelli Haute Couture skirt suit and a staggering Bulgari diamond necklace. The party then moved to Palermo, Sicily, for a spectacular three-day destination extravaganza culminating on Saturday, June 6, 2026, at the 18th-century Villa Valguarnera. The star-studded guest list included Donatella Versace, Sir Elton John and Charli xcx and a DJ set by David Guetta.
