On Friday the young model posted a photograph of baby Nori's tiny hand holding Kendall's perfectly manicured index finger, respecting Kim Kardashian and Kanye West's wishes to keep the youngster's identity private.
"Roommates and best friends :)" wrote Kendall next to the snap on Instagram, which quickly received over 500,000 likes on the photo sharing website.

Kendall's picture of the latest addition to the Kardashian family comes just days after her half-sister Khloé posted a similar image of herself and North.
"NW," the 29-year-old reality star simply captioned the shot, along with a lipstick kiss icon.
New parents Kim and Kanye have been keeping photographs of their daughter to a minimum.
The couple have only released two pictures that show North's face.
