Prince Harry Crashed Meghan Markle's Tiara Meeting with Queen Elizabeth

While we know Meghan Markle and Givenchy designer Clare Waight Keller worked hard on her bridal fashion moment, it turns out that the Duke of Sussex had something to do with it, too.

This fact came to light with the introduction of a new Windsor Castle exhibition highlighting the royal wedding. When Markle went over to her pal Queen Elizabeth's place to pick out a tiara from her grand collection, she had Harry's help and support.

"When it came to the tiara on the day, I was very fortunate to be able to chose this gorgeous art deco style bandeau tiara," Markle recalled in the audio commentary of the exhibition, according to Marie Claire. "Harry and I had gone to Buckingham Palace to meet with Her Majesty the Queen to select one of the options that were there which was an incredibly surreal day as you can imagine."

"I shouldn't have really even been there, but such an incredible loan by my grandmother, it was very sweet,” Harry added.

Ultimately, the tiara chosen was classically simple, and one Harry certainly approved of. “Funnily enough, it was the one that suited the best, the one that looked the best on you without question," he said.

Markle totally agreed.

"That was the one that I think as we tried them on stood out. I think it was just perfect because it was so clean and simple — and also to that point, an extension of what Clare and I had been trying to do with the dress which was have something that could be so incredibly timeless but still feel modern.”

Considering Markle has yet to wear a tiara since, it's fortunate her one moment with one was a win.
