Casually-clad Kourtney Kardashian and Scott Disick prove they are on good terms as they leave Kris Jenner's birthday dinner side by side

They endured a difficult split last summer after almost ten years together.

But it seems Kourtney Kardashian and Scott Disick are still on good terms, after they were seen leaving Kris Jenner's birthday dinner in California together on Saturday night. 

The 37-year-old brunette and her on/off love, 33, appeared to still be comfortable in each other's company as they left the low-key dinner at The Grill in Westlake to celebrate the famous momager's 61st birthday.

Working it out: Kourtney Kardashian, 37, and her ex boyfriend Scott Disick, 33, were seen leaving Kris Jenner's birthday dinner together on Saturday night

While Kourtney had opted for a daring sheer outfit the previous evening, Kourtney kept things more casual and subdued for Saturday night's affair.

The mother-of-three had attended the party in a pair of black distressed jeans, which clung to her slender legs, and a bleached Elton John T-shirt.

She then layered a chic black bomber jacket on top, which featured a chunky silver zip down the front.

Good terms: After an on/off relationship of almost ten years, the troubled couple announced their separation in July 2015 - and have embarked on 'co-parenting' their three kids ever since

Keeping her accessories simple and classic too, the reality star added a pair of oversized Aviator sunglasses and comfy black Vans trainers. 

Leaving her brown locks in their loose, straight style and remaining fairly fresh-faced, Kourtney showed off her natural beauty as she celebrated more intimately with her close family.

Meanwhile her former partner Scott, who she has three children with, seemingly did not feel the need to dress up for the occasion.

The reality star, nicknamed 'Lord Disick', kept comfortable and casual in a simple khaki hoody and black tracksuit bottoms.

Adding black sports trainers and a pair of dark shades, the New York native maintained a low-profile as he headed home alongside his ex girlfriend.

The pair first met in 2006 in Mexico, and went on to welcome three children - Mason Dash, 6, Penelope, four, and Reign, who turns two in December.

However after maintaining an on/off relationship for the duration of their romance, the couple finally announced their separation in July 2015 - and have embarked on 'co-parenting' ever since.

During an interview with Australian chat show Today Extra, the brunette admitted her split from Scott caused her 'a lot of anxiety', which influenced her view towards a healthy lifestyle.

'I was never really an anxious person. I'm usually really calm but when I'm going through something in my life and when Scott and I broke up, I just had a lot of anxiety,' she confessed.

'And so that's when I really stepped up my workouts. Like I would go in some days like shaking.

'I could almost not even...it was so hard to even start my work out,' she admitted.

Keep it casual in some Vans sneakers like Kourtney

After celebrating Kris Jenner's birthday in a sheer dress and lacy bra, Kourtney Kardashian covered up in a t-shirt, jeans and a pair of Vans sneakers.

While to many this may seem like any other shoe, to those in the know they will see more to this than meets the eye as sneakers are usually indicative of fashion's current mood.

When the designer of Celine wore New Balances (and the rest of the world copied her) it showed style was edging away from designer labels towards an athleisure look. The same with Stan Smiths, as they became popular they inched us closer to a revival of the late 90s and early 00s trends (hello the return of All Saints and Juicy Couture!)

And, now we come to Vans. As hot label Vetements is mixing metal music and rebellious youth fashion references on the catwalk it's begun to trickle down to the street, feet first you could say, with the revival of this ubiquitous skater shoe.
