Mum-of-one Jasmine also shared a photo of baby Harper, though her post wasn't as cheeky as her husband's.
In the black and white photo, Jasmine looks on lovingly as her grandmother, sitting in an armchair, cradles Harper.
"Thanks for capturing these special moments," she wrote, tagging photographer Miriam Ackroyd, who captured a series of photos of the mother-daughter duo.
"Absolutely divine Jas....what a precious moment captured," one follower commented below, whilst Jasmine's sister-in-law Sylvia Jeffreys penned, "So special, Jas."
Karl and Jasmine's updates come after shoe designer Jasmine was snapped enjoying a getaway in Queensland with her infant daughter, where she was reportedly visiting her parents and extended family.
In pictures obtained by Daily Mail Australia, the mum-of-one was spotted unloading several suitcases and baby essentials from her car upon arrival at her destination.
The couple purchased a $3.6million beachside property in Noosa, on Queensland's Sunshine Coast, back in April.
According to a report by the Courier Mail, Karl and Jasmine are planning to spend more time relaxing in the Sunshine State with their daughter.
