Kim Kardashian Posts Adorable Instagram Pic Of North West With Kourtney's Kids Penelope and Mason [PHOTOS]

Being away overseas makes the heart grow fonder and Instagram pictures even cuter!

Kim Kardashian has been on a role lately with posting adorable pics of her little one, North West, and in a rare photo opt, Kim posted a picture of North and her cousins – Kourtney Kardashian's children, Penelope and Mason – all together sitting on a couch.

"Missing these three sooooo bad!!!!" Kim captioned the adorable Instagram photo.

As MStars News reported, the Keeping up with the Kardashians star has been traveling around Australia doing various interviews and press meet-and-greets. However, she has been missing her and Kanye West's baby girl a lot!

It seems as thought baby North is in good company as her and her cousins prepare for a cozy pajama party. Mason, 4, and Penelope, 2, look warm and cozy in adorable PJs. And what can be more fun then a celebrity tot sleepover? The adult Kardashian's are a big family and the little Kardashians are going to be no different!

Back in January when North was only 7-months-old, Kim posted an adorable shot of Penelope holding her tightly, "BFF's" Kardashian wrote.

"I love being an aunt," Celebrity Baby Scoop reported, of Kim. "I miss him [Mason] so much. I have Kourtney and Scott send me pictures of Mason all the time."

The eldest of the Kardashian clan began dating Scott Disick in 2006 and gave birth to their son, Mason Dash Disick, on December 14, 2009. His birth was filmed on the 4th season of Keeping up with the Kardashians. Kourtney gave birth to daughter, Penelope Scotland Disick, on July 8, 2012. Two years later, in June 2014 the couple announced that they were expecting their third child together, due in December.
