Just like the rest of us, Billie Eilish was left starstruck after seeing Kate Middleton in all of her golden glory at the UK's No Time To Die premiere.
The Duchess of Cambridge stunned James Bond fans as she walked down the red carpet at the Royal Albert Hall in London alongside her husband, Prince William, Prince Charles, and Camilla.
Middleton was draped in a gold, sequin cape-gown by British fashion designer, Jenny Packham. She paired the look with earrings by the Pakistani luxury label, Onitaa and a pair of matching gold heels by Aquazzura to create a radiant ensemble.
Altogether, the look was worth around $5,000.
During the premiere, the duchess posed for photos with her family and also greeted fans.
Amongst them were other prominent Bond stars including 007 himself, Daniel Craig, and the writers of the movie, Phoebe Waller-Bridge, Neal Purvis and Robert Wade who were all left equally starstruck by Middleton's appearance.
Other stars included the likes of Naomie Harris and Rami Malek.
But there was one meeting that really stole the show for us all...
And that was when Kate Middleton came face-to-face with Billie Eilish and her brother, Finneas O'Connell, both of whom were responsible for the official theme song for No Time To Die, which was initially released early last year.
The meeting was nothing short of iconic.
Who knew these 2 very different world's would collide to create such a magical moment?
From a pop princess to a real-life one, the pair shook hands and chatted for a little while before the duchess moved on.
Both Eilish and her brother appeared in matching all-black outfits. Eilish kept her neat, blonde chin-length hair and signature bangs while Finneas' was on the messier side, but hey, it was still a look, and Kate Middleton didn't seem to mind, so who are we to say anything?
No Time To Die hits theatres in the United Kingdom on Thursday, and in the following weeks for the rest of the world.
