Kim and Kanye West rally to help Kourtney Kardashian with her children in wake of absent-dad Scott Disick’s antics

That is what sisters are for.

Before the world learnt of Kourtney Kardashian's devastating news that she and father of her three children Scott Disick had split, the Kardashian army had already swung into action to do whatever they could to make the impossibly hard time a little easier.

Little sister Kim and husband Kanye West immediately mobilized an action plan to give Kourtney same space taking her oldest Mason with them to New York over July Fourth.

While the 36-year-old - who has not made an official statement but multiple publications' sources have confirmed the split - dealt with her heartbreak in Malibu with daughter Penelope, 2, and baby Reign, six months, Kim and Kanye treated little Mason to a weekend of fun in New York.

Mason, who at five is older enough to realise something is wrong, got a chance to enjoy the holiday weekend with his cousin North, 2.

The Wests and Mason marked the country's independence along with former NBA star Scottie Pippen, his wife, Larsa, and daughter Sophia, 6.

Posting a picture of the children together on Instagram, Kim spoke of the importance of friends and tagged Kourtney in.

The 34-year-old star wrote: 'BFF'S take NYC! @larsapippen & I are so grateful our kids are BFF'S! @kourtneykardash #NYC4thofJuly.'

Larsa, who is Kim and Kourtney's long term pal, echoed Kim's sentiments: 'Sophia, Mason, and North. They don't hangout everyday but when they're together they're always holding hands and hugging just like us @kimkardashian @kourtneykardash.'

The families then spent the day and night of July Fourth abroad a yacht owned by friends J.R. and Loren Ridinger, which sailed around the Hudson River so the children could see the fireworks.

Do fierce fashion in Kim's military style Balmain blazer

She’s a high fashion soldier, so pregnancy isn’t going to stop Kim Kardashian from marching ahead in the style stakes any time soon.

The raven-haired reality star looked ready to hit the runway in her green double breasted blazer from her favorite French fashion house, Balmain, and the luxe wool texture and glistening gold buttons ooze opulence on first glance.

What’s more, Kim stayed true to her inner fashionista and shouldered the chic jacket whilst carrying her daughter North. Now that’s what we call skills, people.

Kim’s fave designer Balmain is the way to go for toughened up tailoring, and this military style blazer featuring an elegant silhouette, sharp padded shoulders and dramatic gold hardware really epitomises Balmain’s vision. Your jacket can’t get much fiercer than this, ladies.

And the good news is that it’s actually available to buy online (YUSSS) so click through to the right to snap it up on MyTheresa.com.

According to the New York Post, it is not just Kim doing everything she can to help her sister.

Kourtney's brother-in-law Kanye has also stepped up in the wake of the collapse of Kourtney's nine year relationship with Scott.

A source told the paper's Page Six: 'Kanye took Mason and Sophia to the movies after Kim and Larsa went to lunch at Cipriani.'

North, according to the source, missed out on the movies as she needed a nap.

While Mason got a chance to have a fun July Fourth, his mom tried to heal in Malibu, California.

The 36-year-old's split with the father of her children was not revealed until Monday but over the weekend she put on a brave face.

Making sure everyone knew she was doing just fine, the star posted a number of pictures of herself on Instagram with daughter Penelope, who turns three on Wednesday.

Looking and doing fine: Whether intentional or otherwise, Kourtney's snaps certainly served as a reminder to Scott as to what he had left behind as not only was she with their adorable daughter, but the reality star was also dressed to impress.

Two days later, it was all but officially confirmed that what many had speculated since the DailyMail.com exclusively revealed the father-of-three was getting very cosy with fashion stylist Chloe Bartoli in Monte Carlo was indeed true.

A source close to the Kardashians told People: She was over dealing with his constant lies and addictions.'

'It was becoming a poor environment for the kids to be raised in and she refused to let that be the case.'

The 32-year-old's struggles with alcohol and trips to rehab have been documented as part of show Keeping Up With The Kardashians.
