Northie loves her auntie Koko!

Kim Kardashian’s daughter North West had a blast on the family’s vacation to Costa Rica earlier this week — and she had even more fun on the plane home! The adorable three-year-old sported her naturally curly hair while she played with Snapchat filters, and she got a little crazy when she grabbed her aunt Khloé Kardashian’s butt.

Kim recorded the clip of her daughter reaching out to touch her auntie Koko’s backside while Khloé showed off her black Juicy Couture leggings to the camera. Northie touched the rhinestones on her aunt’s booty and her mom Kim could be heard in the background saying, “It’s sparkly, huh?”

During the airplane ride home, North also pretended to be a puppy and a bunny — and she got to snack on some cookies, too.

Little Northie wasn’t the only one who got to enjoy the tropical vacay! Her aunt Kourtney Kardashian also went on the trip with her seven-year-old son Mason, four-year-old daughter Penelope, and two-year-old son Reign. The 37-year-old even had some “me-time” when she went out for a late night skinny dip.

Noticeably missing from the family vacation was her on-again, off-again boyfriend Scott Disick — who was banned from the trip after he partied too much at Sundance earlier this month.
