North West and and Penelope Disick rock colorful robes and swimsuits at their birthday party

The famous cousins rock twinning outfits as they celebrate their birthdays in a lavish unicorn-themed party. Kim Kardashian shares videos and photos documenting the family affair.

Kardashian cousins North West and Penelope Disick recently celebrated their upcoming birthdays with a joint rainbows-and-unicorn-themed outdoor bash.

On June 15, Kim Kardashian’s daughter with husband Kanye West turns 4 while Kourtney Kardashian’s daughter with ex-husband Scott Disick turns 6 on July 8. Thus, last weekend, the famous reality TV family got together to throw the little girls a colorful party complete with giant unicorn cakes, floral tablescapes and fur seats.

North and Penelope showed up in matching rainbow-colored robes and swimsuits looking adorable in their twinning looks. North differentiated by wearing a purple unicorn hairband over her slick ponytail while Penelope kept her hair straight and loose. Proud mom Kim shared a video of the coordinated BFF’s along with snaps of the lavish party which was also attended by the rest of the Kardashian clan

Aside from the celebrants’ mothers, aunt Kylie Jenner also showed up with her 4-month-old daughter Stormi Webster. Grandma Kris Jenner and her mom MJ were likewise present along with Kim’s husband Kanye West.

Tons of decorations adorned the party’s poolside setting in one of the family’s Calabasas mansions. There were tables decked out with flowers and balloons shaded under large umbrellas. Guests were treated to chocolate-covered Oreos and donuts, unicorn cones and candy covered pretzel sticks. Party tables were also complemented by white fur chairs with basket bottoms. DJ Livia provided the music assisted by host Big Boy

This is the second time the girls celebrated their birthday together. Last year they also joined forces for a Moana-themed bash.

This year’s party was celebrated ahead of their birthdays probably so it could be filmed and included in the upcoming new season of ‘Keeping Up With The Kardashians.’ Its first trailer has just been released with Kim revealing season 15’s premise saying “things have really changed.”

A lot indeed has changed. Apart from Kim welcoming her third child Chicago, Kylie welcoming first child Stormi and Khloe welcoming True, there’s also that whole other issue concerning Khloe’s baby daddy cheating on her during her pregnancy. Kim has also been busy lately launching a new perfume and make-up line and lobbying for prison reform at The White House.

Meanwhile, Kourtney is expected to open up about her personal life including her relationship with Younes Bendjima while Kendall furthers her modeling career at the runway. Also seen in the 30-second trailer is new mom Kylie driving one of her many luxury cars.

Season 15 is due to premiere in the summer though it’s actual release date has yet to be revealed.
