Archbishop of Canterbury Justin Welby seemed to struggle to fit the royal crown on King Charles’ head during the crowning moment at the coronation, held at Westminster Abbey, on Saturday, May 6, making for a briefly embarrassing moment.

As people worldwide watched keenly as the moment that they all had been waiting for arrived, Welby took the crown in his hands, raised it up above Charles’ head, and slowly brought his hands down to place it on the British monarch’s head.

However, he struggled to keep it there. Royal fans were shocked to witness the precarious moment as the royal crown threatened to fall off any second, which could have led to a scandalous moment in royal history. Watch the moment here:

The bishop seemed to slightly lift the crown a second time after placing it on Charles’ head and place it again more firmly, to make sure that the position of the crown was secure on the monarch’s head.

Meanwhile, royal fans took to social media to mock the moment. One wondered where there would be a “Cinderella-style hunt” for a head in the crowd of attendees who fit the crown. The crown, however, eventually settled on Charles’ head, unmoved.

Welby finally let go of the crown and bent down to peer into Charles’ eyes to make sure that he was comfortable wearing the crown. “I come not to be served, but to serve,” the King said in his first prayer after reaching the abbey.

Welby opened his sermon with, “We are here to crown a King, and we crown a King to serve,” the Archbishop opened his sermon with. The King of Kings, Jesus Christ, was anointed not to be served, but to serve. He creates the unchangeable law that with the privilege of power comes the duty to serve.”

The crown in question was made for King Charles II in the 17th Century and is only worn when the monarch is crowned.
