There's officially a new Mrs. Beckham in town!

This weekend marked the much-anticipated nuptials of David and Victoria Beckham's eldest son, Brooklyn, and actress (slash heiress) Nicola Peltz, the daughter of billionaire businessman Nelson Peltz. 

Needless to say, no expense was spared for the wedding of these two young scions.

Rumored to cost $3.5 million, the glittering three-day affair was held at the Peltz family's Palm Beach compound, where A-list guests including Venus and Serena Williams, Eva Longoria, Gordon Ramsay, Rashida Jones, Kiernan Shipka, directors Michael Bay and M Night Shyamalan, and yes, even fellow Spice Girls Mel B. and Mel C. celebrated the main event oceanside with a black tie dinner and DJ set by Marc Anthony.

The bride wore a custom Valentino gown to say "I do," which, according to Vogue, featured a secret "something blue" message from her mother, former model Claudia Heffner Peltz, embroidered into the skirt. Meanwhile, as a little surprise for her husband-to-be, Nicola had a special label sewn into Brooklyn's Dior suit, which he wore with a diamond lapel chain by Anita Ko - a gift from his new in-laws.

Despite the swarm of paparazzi and star-studded guest list, the event managed to stay mostly under wraps on social media - until, of course, the newlyweds finally decided to share a peek inside themselves.
