Sienna Miller

Technically, this is the "ATG Summer Party hosted by Ambassador Theatre Group CEO Mark Cornell and Sienna Miller in support of Sir Sam Mendes and his Theatre Artists Fund at Kensington Palace," and I really regret not writing scene in The Heir Affair wherein Bex Porter was spying on an event like this out of her bathroom window and yelling things back at Nick like "SIENNA MILLER APPEARS TO BE WEARING A NIGHTGOWN." (Actually, in thinking about it, I think Nick would be doing the reporting. I HAVE NOTES ON MY OWN WORK.)

Jenna Coleman

This is very summery and sweet.

Omari Douglas

Omari and I have both been on the lookout for some wide-legged black trousers this summer, I see. He's had more luck than I have!

The Redmaynes

Hannah looks cute but also maybe a little casual for this event compared to everyone else? Eddie Redmayne needs to tell his stylist to turn down the styling gun about 15% because he looks SO STYLED that it is veering into silliness. People still need to look like it's possible they woke up and decided what to wear themselves.

Alice Eve

This is pretty! I feel like Hannah Bagshawe was like, "I HAVE like eleven flowered party dresses? WHY didn't anyone TELL me? Was everyone too busy looking for Eddie's sweater vest?"

Harriet Walter

All hail Harriet Walter, who I assume is here -- as she is in all productions -- to elegantly ruin our lives.

Jane Horrocks

BUBBLE! (No better time to suggest you revisit our AbFab retrospectives; Bubble got her own!) She looks great and has not aged a day.

Elizabeth McGovern

In which Lady Grantham turns to camera to greet us all in the opening credits of the new show about her life, Everything's Coming Up Cora.

Elizabeth McGovern and Dominic West

I sincerely laughed out loud at this photo. It looks like Elizabeth McGovern is leaning over her cubicle wall at a wild party down at the office.

A Bunch of Recognizable Brits Had a Party at Kensington Palace Over the Weekend

Like, in the gardens. Not in Kate's living room or whatever.
