"Aunt Taylor came to meet Genevieve and the other babies last night 😺😺😺😺 💕," he captioned the post.
Swift was clearly smitten with JVN's cat, writing: "Genevieve of the House Van Ness, First of Her Name, the Unscratched, Queen of Meows and nose boops, Catleesi of the East River, Breaker of Wine Glasses, and Mother of hairballs."
The 32-year-old hairstylist loved her response and posted it on his Instagram Story. "F**k me up with this caption. I wasn't ready," he remarked.
