I came in through the backstage/VIP entrance to The Tent and she was right there, having her photo taken! I was standing right behind the photographer when this photo was taken.
I then went into The Tent to see the Michael Kors fashion show. A few minutes before the show started (40 minutes late), Sigourney walked into The Tent. She posted for photos, and I got a poor photo of her posing for those photos (look in the center of the photo below).
