Kim Kardashian's daughter is "best friends" with her older sister's children.
The 'Keeping Up with the Kardashians' star has a six-month-old baby girl, North West, with her rapper fiancé, Kanye West, while her sibling Kourtney has a son, Mason, four, and 17-month-old daughter, Penelope, with her long-term boyfriend, Scott Disick, and they all "get on" extremely well.
The 33-year-old beauty told fans during a Q&A with MobioINsider.com on Sunday (22.12.13): "It's so cute how they all love each other so much! Penelope & North are bff (best friends forever)!"
She added: "Mason bosses them around and is super protective."
Meanwhile, Kim, who has been travelling throughout the US recently with Kanye while he performs his Yeezus tour, is looking forward to spending Christmas with her entire family at her mother Kris Jenner's house in Calabasas, California.
She said: "Kanye, North, mom, sisters, step dad, brother, niece and nephew, everyone! They are all my family and we will all be together! I can't wait."
The reality TV star also revealed she is thinking about dying her hair back to her natural black.
She said: "I'm not sure. I had the urge to go dark today when I was at the salon but I finally got the colour blonde so good, I want to wait a little longer. I go back and forth all the time on what colour I want my hair."
