"We're excited, because we studied and read Ernest Hemingway," Kourtney says. "And it's cool to see how people live."
At one point, the tour guide shows the sisters Hemingway's private bathroom, noting, "He'd check his weight almost every day, and take notes on the wall."
"That's like me!" Kim interjects.
The 35-year-old mother of two of course, has been very vocal about her weight loss journey following the birth of her son, Saint West, in December 2015.
