“I get a lot of comments about my body, which is nice. But he came in and messaged me something like, ‘You have the most beautiful smile,’ and sent me his favorite photo of me from my feed,” Kourntey said.
It wasn’t one of the many swimsuit shots she has on her account.
“I was wearing a turtleneck in that picture,” she said. “It was really sweet of him.”
