Will dislike of Chloe Sevigny ruin this for me?

No...she's not. I did a photoshoot with her a few years ago. We brought the jewelry to be used for the shoot and they needed us to stick around. It was an outside shoot and it was very hot that day. We (my driver and I) had no provisions, and someone from the crew was tasked to get water and food. When the supplies arrived, we were not offered any food or drink. We were sitting in our vehicle when Chloe walked up to us with a handful of bottled water and sandwiches. Before that moment, I did not know who was involved in the photoshoot, but was shocked to see her approaching. She introduced herself and said she figured we could use some refreshments. We talked about the shoot and the weather before she was called back by the crew. A very nice gesture from a very down to earth young lady!
