Cindy Crawford's daughter Kaia Gerber, 16, looks tired as she steps out after chalking up another big modeling campaign

Cindy Crawford's daughter Kaia Gerber is quickly becoming one of the most in-demand young models in the industry.

And it seems all the hard work is catching up with her. 

The 16-year-old stepped out in Santa Monica looking rather tired and pale on Friday.

She wore double denim with a retro Boyz in the Hood T-shirt while running errands.

She has just landed another big modelling contract, starring in Calvin Klein's new Spring 2018 campaign with her big brother, 18-year-old Presley Gerber.

The famous offspring both posed for solo shots for the designer, as well as a loving brother-sister snap.

Photographed by Willy Vanderperre, the ads are part of #MyCalvins ads, which are titled 'Our Youth'.

Put your best foot forward like Kaia in Converse

When it comes to off-duty attire, nothing is more essential than comfortable shoes. And when it comes to comfortable shoes, no kicks are more iconic than Converse All Stars.

Worn by the likes of Kendall Jenner, Gigi Hadid, Rihanna and Kaia Gerber, Converse's Chuck Taylor kicks are the perfect accompaniment to any and every outfit.

Which is why we have to praise Kaia Gerber for her sensible yet stylish off-duty attire, teaming a denim jacket and shorts combo with a pair of classic Converse. Supermodel in the making, right?

Forget beautiful heels that you regret putting on, when you’re on the go you need functional fashion, which is why we have created an edit to go alongside Kaia's pair (which you can buy using the link, right) of our favourite similar styles when it comes to canvas shoes. Shop the carousel below.

'The evolved #MyCalvins concept has family at its center,' a press release explains. 'This campaign captures these bonds and brings to life different ways we can inspire families — both born and made — to connect with one another, and celebrate the things that unite us.' 

In one image, they sit together on the floor, with Presley's arm slung protectively over his little sister's shoulders.

Kaia, the spitting image of her mother, looks moody in a denim jacket and leather boots, while Presley dons matching footwear, a denim vest, and a logo baseball cap.

Kaia made her Calvin Klein debut on the runway in New York this past fall, though this is her first set of ads for the designer. Presley appeared in the Fall 2016 camapaign. 

He, too, was happy about the partnership, writing: 'Honored to be part of this campaign with @KaiaGerber.'

In September they both appeared in another fashion ad together for Omega watches, but that time the entire family was involved.

Mom Cindy — who first worked with Omega in 1995 — and dad Rande also starred in the ads and were proud to share it with their children.

'I've been in the Omega family for years, but I finally get to share it with these three,' said Cindy.

Before that, Kaia and Presley had posed together for CR Fashion Book on numerous occasions. They were also shot for W magazine in 2016.
