The video, which was shot between the 49-year-old's legs, showed the model stretching in the sun in her orange and pink bikini.
"Monday 🌝 🏝😎❤️," Heidi captioned the clip.
It comes after the mum-of-four shared a topless snap of herself wearing just a pair of white bikini bottoms, with the caption, "My hot girl summer 2022."
Heidi is definitely not shy and just last week shared a black and white nude photo of herself lying in bed.
Fans joked about the model's Instagram posts on Twitter, with one user writing, "#HeidiKlum's latest Instagram caption should be 'I need attention.'"
"Everytime Heidi Klum posts on Instagram I have to take a break from the app," another said.
"Heidi Klum been acting up on the gram 😅," a third wrote.
"Heidi Klum's IG is 👀," a fourth added.
Heidi Klum's daughter shocks with 'dangerous' detail in bikini snap
It comes after Heidi's daughter Lent worried fans with her latest bikini snap, with some labelling it as "dangerous".
The star has been on a beach holiday, sharing snaps of herself enjoying the warm weather and lounging by the pool.
Her followers noticed that the 18-year-old model may have overdone her time in the sun, with many begging her to take action.
Posing in a skimpy ‘upside down’ bikini, Leni revealed not only her figure, but also her severely sunburnt skin.
“A little past sun kissed,” she joked in the caption, prompting followers to reprimand her.
“LENI!!!!! Wear your sunscreen!!!!!” one fan exclaimed.
“Coming from a person that has had 3 skin cancers removed…USE SUNSCREEN!” wrote another.
“Ouch. That’s gotta hurt. Take care, Leni,” added a third.
After posting a set of selfies with her friend Ayva Magna, followers were dismayed to see that Leni’s skin was still extremely red.
“Be careful from that burn Leni, that’s so dangerous on your gorgeous skin!”
