When Prince Harry and Meghan Markle tied the knot in 2018, it was the biggest event of the year. Guests quickly realized just how far the organizers went to keep things under wraps.

Famous faces from both the royal world and celebrity circles were there in person, while millions more watched the ceremony live from the comfort of their homes.

Although Meghan was no stranger to the spotlight thanks to her acting career—especially her role on Suits—nothing prepared her for the intense attention leading up to the wedding.

Like anyone else, the pressure took its toll on Meghan and Harry. Less than two years later, they stepped away from royal life and started fresh in the US with their two children, Archie and Lilibet.

The big day had to run perfectly—after all, nobody wants their wedding turning into tabloid drama.

Tina Brown, author of Palace Papers, described the lead-up to the wedding as a complete “s*** show.” She said an insider told her it was “all drama, all the time,” and palace staff were “fed up” with the long list of demands from the couple.

To keep things from spiraling and prevent leaks to the press during the ceremony and party, the guards stepped in with a strict warning for everyone attending.
