Kendall, who would have had to drink one thousand-year-old eggnog if she decided not to answer, thought copping some light wrath from her sisters was a better way to go about things.
Before Kendall answered, Harry got his sassy pants on and joked: "I feel like I could answer it."
"They are all amazing," Kendall begins.
"Rob is No. 1," Kendall says. "He’s so good to his daughter. That’s so hard, they’re all amazing. Then it would be, like, Khloé, Kim, Kylie, Kourtney. They’re all amazing!"
Kylie coming in second last and Kourtney as last has got to hurt.
Interestingly, that was the only question Kendall decided to answer, choosing to drink a salmon smoothie rather than share the most unlikeable supermodel and eat a bull's penis over sharing who was the most interesting celeb to slide into her DMs.
