Bee Shaffer and Lilly Burns: Safe from Everything But Ernie Anastos

I honestly don't know how else to caption this tipster'd photo of Bee ShafferAnna Wintour's daughter, right—and two friends, one of whom is dressed as a sparkly chicken. This looks like the most fun night ever. Explanations? Update!

We're now told the girl on the left is Lilly Burns, daughter of Ken. So imagine this panning over and zooming in on this photo while Morgan Freeman talks over it. [Ed. She's never heard that one before.]

Also, any ideas for captions in comments. The winner gets theirs up and possibly a sparkly chicken outfit. No promises.
