Empty ghế, chỗ ngồi tiếp theo to Hugh ;))) 

it could mean anything :)

here's a more complete set of the seating position link

lol. Nice but that's not what it means. They just show where the nominees are sitting with pictures. Their dates don't get photos on their chairs nor anyone else. I think it's for rehearsal, so the camera guys know where everyone is for the various shots during the main event, and they're not left searching for people.

if it's Lisa who's going to sit next to Hugh,they don't even have a picture of her?>:(
