Even a ceremony as grand as receiving a damehood couldn't stifle Emma Thompson's quick wit.
The Oscar, Golden Globe and Emmy-winning actress and writer received the title of Dame on Wednesday from Prince William, and managed to fluster the Duke of Cambridge in the process.
"I love Prince William, I've known him since he was little, and we just sniggered at each other," Thompson told The Daily Mail. "I said, 'I can't kiss you, can I?' And he said, 'No, don't!'"
The 59-year-old added. "If you're first up, you have to be more formal on such an occasion, but he's looking wonderful and doing so well. He said, 'This day isn't about me, it's about you.'"
Thompson has been a longtime friend of the royals, and was honored to be part of the moment with the man she saw grow from a young child.
"It’s really lovely, because I’ve always loved the boys and I’ve always been a long-term correspondent with their dad. It’s a very lovely feeling," she said.
The newly minted Dame was recognized in the Queen's Birthday Honors list in June, and was joined by her husband, Greg Wise, and their children, Gaia, 18, and Tindyebwa, 19, for the ceremony.
Now that she's officially a Dame, don't think that will stop Thompson from speaking her mind.
"I’m very outspoken, politically. I’m a card-carrying feminist, human rights advocate, so good for them, because the establishment need more people who can speak up for those things," she said of the honor.

This is so '90s, and we totally dig it. Plus, the silky fabric looks comfy!

Well, we can't say it's our favorite look. But hey, this way she can go home and hop in bed after seeing the premiere of "Sense & Sensibility," no need to change!
Emma looked simply stunning in this look, made complete by her glowing skin and shiny blonde locks.
An edgier look is fitting when you come to New York City, but we wish this one had been toned down a bit -- it's never our fave to do bold makeup AND a bold dress!

These ladies are looking glamorous (even if with a bit more fabric than we'd like to carry around) at the White Tie & Tiara Ball.
Emma looked gorgeous in this trick-the-eye metallic and green gown.
At the premiere of one our our favorite movies (of.all.time.) "Love Actually," Emma wore plum in velvet, fur and satin from head to toe!
Emma rocked red and pink together(and dare we say flames?) at the Evening Standard Awards.
As you'll see over the next several photos, Emma is clearly a fan of large fur shawls!

Emma Thompson went all out in a '20s flapper dress and accessories that we LOVE during the Lavender Trust Party in London.
We might not choose to wear sneaks to a Chanel runway show, but at least Emma is comfy! Can't say the same for the women walking around those shows in 5 inch heels.
Thompson is loving this bright fun pattern of this dress, which she wore to the world premiere of "Last Chance Harvey."
Emma adds a pop of color to this classic ensemble with a bright blue clutch.
From her hair to the top and the long coat, this look is all about volume volume volume!
We love this outfit on Thompson -- her hair is divine, the dress and coat are totally chic, and we're obsessed with those shoes!

Grace. That's what we have here, ladies and gents, a class act. Thompson looked stunning at the Harper's Bazaar Women of the Year Awards.
Black and white is always a winning combo in our book, and when you put it together like this, we love!
