The Keeping Up With The Kardashians clan are a tight-knit family, as proved by Scott Disick's latest comments about Kim Kardashian.

Kourtney Kardashian's ex Scott recently bigged up his kind-of-sister-in-law on Instagram, calling one of her bikini photos "hot".

40-year-old Kim shared a series of swimwear snaps in support of Kendall Jenner's tequila brand 818. In them, she's wearing a green bikini and baseball hat, lounging on the grass next to a bottle of the spirit.

"Supportive Sister 8️⃣1️⃣8️⃣ 🌵" she wrote to her 235million followers.

Unsurprisingly, the comment section was full of people praising Kim's pics. "We love to see it ❤️🙌," one person wrote, while another said, "Omg!" and added lots of fire emojis.

But it was Scott Disick's comment that caught the most attention. "Hot Moma," he wrote, which has since had over 1.7k likes and 40 comments.

Fans have praised the pair for their supportive relationship. Kim is auntie to Scott's three children with Kourtney - Mason, 11, Penelope, 9 and Reign, 6. Despite Scott and Kourtney's split, he's still big in with the KUWTK crew, who have been photographed out to dinner with his new girlfriend, Amelia Hamlin.
