Kourtney Kardashian steps out in skin-tight leather trousers and bodycon top as she joins her famous family at Nobu bash

She kicked her long-term partner Scott Disick out of their family home earlier this summer.

And Kourtney Kardashian, 36, was showing the 32-year-old star what he was missing as she attended a Westime private event held at Nobu in Malibu to celebrate her showbiz momager Kris Jenner's new Haute Living magazine cover.

The Keeping Up With The Kardashians favourite looked sensational in skin-tight leather trousers and a long-sleeved, bodycon top that clung to her curves in all the right places as she arrived at the venue on Monday night.

Go hell-bent for leather in Kourtney's Alice + Olivia leggings

Even by their own standards, the Kardashian/Jenners have had a busy couple of weeks.

After celebrating the big 1-8 with Kylie and a sun-soaked holiday on St Barths, they're back home toasting yet another magazine issue fronted by a member of their famous family. For once it's not Kim. It's Kris who's featured in Haute Living. But another sister stole the limelight from the momager!

Like Kylie and Kendall, Kourtney got the khaki memo for their night at Nobu, teaming a pair of leather leggings with a matching crop top and barely-there heels. Her super skinny trousers are by Alice + Olivia and they show off her incredible pins to perfection.

Kourtney gave her younger sisters a run for their money in her tight clothing, which made the most of her pert derriere and flashed a hint of her stomach.

She paired her figure-hugging outfit with a pair of sexy black stilettos and a cute leather handbag.

Kourtney wore her long raven locks down loose and opted for a pared back make-up look with just a hint of mascara and lip gloss.

The mother-of-three left her young children Mason, five, Penelope, three, and eight-month-old Reign at home for the evening as she caught up with her siblings Kim, Kendall and Kylie.

Sharing a snap of the stunning sisters on social media, Kourtney posted, 'Nobu with my Booz'.

The star also raised eyebrows by posting a cryptic tweet that appeared to be aimed at her on/off partner Scott.

'Insanity: doing the same thing over and over again and expecting different results. Albert Einstein', she wrote on Twitter.

Her comment comes as her ex-partner of nine years, Scott, was spotted looking rather worse for wear as he left Matsuhisa restaurant in Beverly Hills.

The pair have had well-documented spats about Scott's excessive partying and drinking on Keeping Up With The Kardashians over the years, but things came to a head this summer when Lord Disick was pictured cosying up to former flame Chloe Bartoli while Kourtney was home with their children.

They sparked reconciliation rumours when Scott shared photos from their former family home over the weekend, but it seems it was just a flying visit.

A source told TMZ: 'Although Scott was posting pics insinuating he's back at the family homestead, a reconciliation is not in the works. He was just visiting the kids.'
