While we're not sure if self-professed GoT fan William had the chance to catch up on the latest series with the actress, it's pretty cool to know they were working closely together on the evening alongside other stars, such as TV presenter Jonathan Ross, and Downton Abbey creator Julian Fellowes.
After the event, Emilia shared a hilarious photo of herself laughing at one of the evening's fine courses: eggs.
"That moment when you find your gold leaf baby (dragon)eggs..... at Kensington palace," she joked in the caption.
The star also shared a heartfelt message about the important night on Instagram, writing alongside a boomerang: "This evening has been magical for so many reasons, @troymagician made that literal. The plight that so many young people face as a result of homelessness can seem insurmountable but tonight I met and heard about those incredible young people who made it not only possible to turn it around but soar and survive instead. 💪🏻🔥 @centrepointuk hella yeah. 👌🙌 "
