Kim Kardashian's 6-month-old daughter already has a best friend--her bigger cousin Penelope Disick!

The 33-year-old Keeping Up With Kardashians reality star told fans on the social networking Q&A site, MobioInsider that "Penelope & North are BFF's."

"It's so cute how they all love each other so much!" the new mom added.

Kim said that North's older cousin Mason, 4 "bosses [both of] them around and is super protective."

Looking forward to celebrating Christmas, Kim said, "They are all my family and we will all be together" at her mother Kris Jenner's family home in Calabasas, Calif.

Kim, Kanye West and baby Nori have been living with Jenner as their house is currently being reonvated. 

Though it has been quite tough with having the house full with Kim's family and teenage daughters Kylie and Kendall, Kris is loving the time she has with her family. 

"The whole way it evolved has been a dream come true for me, as her mom and ... North's grandmother," Kris told PEOPLE. "Our house is blissful. To watch Kim and see her mature and grow and turn into the most delicious mother, who is interested and engaged and reads to her every day, and if she works, brings North with her - it's very cute the way she doesn't want to be apart from her."

Kim and Kanye recently headed to the movies on Friday night to check out the rapper's cameo in Anchorman: The Legend Continues. The couple held hands as they left the movie theater and left in a Range Rover.
