Brooklyn Beckham and Nicola Peltz: $3.5 million - $4 million

What happens when the nepo baby of a pop star and a sports legend ties the knot with the daughter of a billionaire businessman? A huge wedding happens!

Brooklyn and Nicola took over her family’s massive $103 million oceanfront Palm Springs estate for a three-day celebration. Because venue rental costs were non-existent, the budget was channeled into unparalleled opulence. The bride wore a custom Valentino Haute Couture gown that required a year of sketches and multiple transatlantic trips to perfect, valued at a staggering $250,000. Guests drank free-flowing bottles of rare Bollinger champagne and dined on menus curated by a former White House personal chef, all while Snoop Dogg flew in to perform a live DJ set.

Now, the nuptials are famous for THAT dance that Brooklyn's now estranged mother Victoria Beckham did at the reception.
