Little North West and Penelope Disick are great friends and the latter paid tribute to her cousin when she stepped out with her mother Kourtney Kardashian and her brother Mason wearing a T-shirt that had the name of North on it. The little girls are best friends and often attend ballet class together.

Penelope was dressed in an all-black look during an outing over the weekend with Kourtney. The toddler’s outfit consisted of a sleeveless T-shirt with high neck. It featured “What Would North Do?” written across it in glittering gold letters.

The blonde tot’s T-shirt is by an Australian designer, Madeline’s Pocket. The actual version of the T-shirt has short sleeves. But, most probably Kourtney ripped off the sleeves to create a fitting tank top for her daughter.

Madeline’s Pocket is a family run business. It was started by a couple Erica and her husband Carl after using modern cloth nappies on their son. When their daughter was born in 2014, they extended the range to include baby leather moccasins top knots and wall decals.

Penelope teamed the T-shirt with a pair of black leggings and trainers. Kourtney had taken three-year-old Penelope and her brother Mason, five, to the movies in Calabasas. Their little brother Reign, who will be one on Dec. 14, had stayed at home, possibly with his grandmother Kris Jenner or father Scott Disick.

The cousins have been spending even more time together as Penelope's parents are currently separated. Scott was in rehab a few weeks ago to deal with some personal issues. The tots have always been inseparable, be it going to Disneyland together or to ballet classes.

The best friends forever were spotted during a trip in Calabasas, Los Angeles on Nov. 18. While Nori was trendy in a distressed jeans and jumper, Penelope wore rolled up jeans and patent black Doc Martens. Her golden-brown locks were pulled up into a high topknot with wispy bangs framing her face.

However, mini-fashionista Nori matched her look in a pair of sporty blue converse trainers. Her curly hair was left loose, the top of which was secured by a barrette. She showed off a pink satiny handbag with her outfit.

She proved that she is a pro as she kept the shiny pink bag hanging in the crease of her arm in real showbiz style. The kids had an outing with their nannies as North’s mother Kim Kardashian West completed her Christmas shopping at a nearby store.
