Kendall's turn! The Kardashian and Jenner sisters just can't get enough of baby North West! On Friday, Oct. 18, Jenner shared a sweet photo of Kim Kardashian and Kanye West's baby girl via Instagram. 

"Roommates and best friends," Jenner wrote with a smiley face.

In the picture, the 17-year-old model shows baby North, 4 months, reaching out to hold on to Jenner's index finger. North's face isn't visible, but her sweet outfit is -- white pajamas!

Just three days prior, big sister Khloe Kardashian posed for a similar shot. Her photo, also covering North's face, showed the 29-year-old cradling her niece's little arm. "NW," the Keeping Up With the Kardashians star simply wrote alongside the photo. She also added a lipstick emoji icon.

Kim, 31, and the Yeezus rapper, 36, are currently living at Kris Jenner's home in Calabasas, Calif. In mid-September, the couple was spotted overseeing renovations for their new home in Los Angeles. "It's not close to being done, but it's coming along," a source previously told Us Weekly.
