The most expensive modern wedding was that of Khadija Uzhakhova and Said Gutseriev, funded by the groom’s father, oil and media magnate Mikhail Gutseriev. The lavish celebration featured a $1 million Elie Saab gown, floor-to-ceiling floral décor, a nine-tier cake, luxury vehicles, performances by Jennifer Lopez, Sting and Enrique Iglesias, and jewelled keepsakes for 600 guests.
