Taylor Swift and Travis Kelce are officially engaged, and America's royal wedding is now on the horizon. They may be one of the world's most famous couples, but the fact that they kept their own relationship status update confidential for two weeks suggests their big day prep will likely be one of the wedding industry's best-kept secrets.

For a celebrity union of this magnitude, anyone involved will likely need to sign NDAs, if they even find out who they're working for at all. Event planner Bianca Blag, who has planned weddings for high-profile clients, tells Yahoo she wouldn't share the name of a prominent bride like Swift with the vendors working to bring the event to life at all - except maybe the photographer, who couples often want to have "a personal intimate relationship with" ahead of the big day.

It's a lot of secrecy for something that's going to set trends and become one of the most copied events for years to come. Blag predicts that the Swift-Kelce nuptials will be intimate, ethereal and a bit whimsical, with a silly and fun component. Ever the "Mastermind" who has imagined a number of weddings and marriages in her own lyrics, Swift might have already plotted what she wants for her big day.

Privacy is the new luxuryBlag doesn't see Swift and Kelce copying Jeff Bezos and Lauren Sánchez's lavish Venice wedding, with its "look at us" headline-grabbing energy and star-studded guest list. Though the pop star is more of a trendsetter than a follower, she'll likely be part of the recent shift among A-listers who traded public spectacles for private ceremonies. Demi Lovato, Hailee Steinfeld, Kristen Stewart and Millie Bobby Brown are recent brides who managed to keep their weddings mostly under wraps until they were already a "Mrs."The approach allowed them space to enjoy the moment - and control over what, if anything, they shared publicly. Event planner to the stars Sharon Sacks tells Yahoo that she's seen celebrity weddings move away from extravaganza toward intimacy."They've shifted from that over-the-top production to a smaller, intimate feeling affair," she says, noting a renewed focus on family and close friends. Also, "timeless elegance" is in style more than ever, with brides embracing the "beauty of vintage" and "not looking for the ordinary."AdvertisementAdvertisementAdvertisementAdvertisementPrivacy remains of the utmost importance. In the nearly 40 years that Sacks - who has planned weddings for Kim Kardashian, Meghan Trainor and Nick and Vanessa Lachey - has been running her business, she's developed her own playbook for keeping high-profile weddings under wraps, from hiring decoys to locking down airspace."We're their SWAT team," Sacks says. "You name it, we do it all."Celebrities go to great lengths for privacy on their wedding day - and we talk to the professionals who help make that happen.

Sharon Sever, who's the head designer for bridal and evening couture fashion label Galia Lahav, tells Yahoo that he's personally flown gowns to A-list brides to ensure that nobody, especially the pesky paparazzi, steals a sneak peek."It is really about protecting the moment," says Sever, who has made bridal dresses for Brown, Beyoncé, Simone Biles and Paris Hilton. "A wedding gown is personal, even if the bride has millions of followers."Code names and decoy dresses are par for the courseSever collaborated closely with Stranger Things star Brown to design the gown for her 2024 wedding to Jake Bongiovi, son of Jon Bon Jovi, a process he calls unforgettable."Millie is the definition of today's modern bride - she's stylish, funny, emotional and knows what she wants without being overcontrolling, and that is a rare gift," he says. "We didn't do endless back-and-forth sketching. Her vibe was clear and loud to me. It had to be romantic, fresh and unexpected. She gave the vision, I translated it into fabric.
