Kim Kardashian threw daughter North a no-expense sparred birthday bash as family and friends celebrated her 10th birthday in style.

The group of youngsters boarded a party bus in bright pink pyjamas as the Barbie-themed bash got underway. Kim, 42, chaperoned the group along with sister Kourtney as the older Kardashian’s seemingly put their recent differences to one side.

The excitable kids were seen living their best lives as they cruised around LA in the fancy bus which had been kitted out in black and pink balloons.

The event took place on Wednesday before the sleepover party saw the crew stay in a fancy hotel in the city ready for North’s actual birthday on Thursday.

They were all seen posing for pics throughout the bash with North leading the way with rockstar style poses. Mum Kim was in the back of the shots doing her trademark pout while throwing peace signs in the air.

They took the party to a large garden area where Kim and Kourtney watched over the youngsters in their matching pyjamas.

Each set of the pink outfits had their own personal touch with their names stitched into the left hand side of the chest.

Kourt completed her look with a leather black jacket, which she carried over her arm, and a pair of black sunglasses.

The outing follows speculation Kim and older sister Kourtney have had a strained relationship recently.

In a recent episode of The Kardashians, the POOSH founder admitted she actively avoids her younger sister.

Speaking to sister Kendall Jenner, 27, the Kourt confessed she “stays a little away” from Kim, who she insists doesn’t know what is driving her.

In the teaser clip Kourt and Kendall get candid about their sister, with the elder sibling describing Kim as “crazy”.

She revealed that is why she sometimes tries to “law low” before adding: “That’s what I always say. I try to keep my distance and, like, do my own thing.”

Kendall replied that she thought life is “fast” for the SKIMS founder at the moment, with Kourtney agreeing. Kourt admitted Kim was “really driven” but shared concern, saying she “doesn’t know what’ driving her”.

“If you don’t know what’s driving you, I think it’s definitely hard to feel. What are you doing it all for?” Kourtney asked.

The pair both agreed that no matter what is happening, it’s Kim’s life to live and Kourtney confessed that the only time it will bother her is if issues “bump into” her own life.
