It's long been established that Prince Harry knows how to let his hair down. We just didn't know he did it in the company of superstars.

New photos have surfaced of the royal partying at a pre-Christmas celebration thrown by model Suki Waterhouse several weeks ago. Harry's playmates will look familiar: There's actress Sienna Miller, Suicide Squad stars Cara Delevingne and Margot Robbie, presenter Poppy Jamie, and his own cousin, Princess Eugenie. Pity nobody invited Will and Kate.

Alas, the original Instagram showing Harry's party antics and rad neon green specs has been taken down. Did Grandmother have a word?

Here's a screenshot of the party snap in question, plus other star-studded photos from the evening. Think they'll take the party to Buckingham Palace next time?
