Kourtney Kardashian balances youngest child Reign Disick on her slender hips as they spend a dedicated mother-son day out

He's the most rarely seen of the third-generation Kardashians, aside from baby Saint.

But Reign Disick was spending some dedicated time with mum Kourtney Kardashian on Wednesday, while his brother Mason and sister Penelope were absent.

Mum-of-three Kourtney, 37, balanced the one-year-old on her slender hips as she spent a day out in Calabasas, California in her gymwear.

Little Reign bore a striking resemblance to father Scott with a mop of blonde hair that contrasted the familiar raven-coloured Kardashian tresses.

The toddler was barefoot with his sleeping cloth in hand while Kourtney wrapped a protective arm over his chunky baby legs.

Kourtney looked youthful beyond her years with her hair scraped back and her Taylor Morris Eyewear mirrored shades perched on her nose.

She was also making a remarkable show of her slender figure, one year after welcoming a third child with ex-partner Scott.

The stunner was firmly in gym mode, dressed in skintight workout leggings with a vest and sports bra, teamed with a pair of sporty trainers.

Kourtney's eldest children Penelope and Mason were nowhere to be seen, despite being the more photographed of the trio.

Shield yourself from the glare with these futuristic sunnies by Chanel

Kourtney Kardashian is knows how to perk up an otherwise simple outfit. We spot her a simple black bikini but what adds serious oomph are her Chanel mirrored sunglasses.

Chanel is always a good investment since it never goes out of style. While these are definitely on the more fashion forward side, get them knowing you'll be ahead of the crowd. With Rihanna's about to release her collaborative Dior shields, you know these Chanels are about to blow up the shield trend. These are sure to be the next must have sunnies because of their distinctive shape. Furthermore since they're oversized, they'll hide all those endless nights of summer partying perfectly.

Sadly this pair is already sold out online. Head over to the right to check out more chanel sunnies or if you need some shielding right now, check out the edit below for some budget-friendly lookalikes. Or go splurge on those amazing Karen Walker look alikes.
