The model took to Instagram to post a clip of herself in a promotional campaign for Waterdrop, a reusable glass water bottle.

She also sported another outfit, a curve-hugging patterned bodysuit with extravagant feather detailing on the top with 80s style teased hair.

In the caption, she wrote: "As a great poet once said 'we don't inherit the earth from our ancestors, we borrow it from our children' -Emerson.

"It's my goal this New Year to use less plastic! Join me and @waterdrop in leaving the planet cleaner than we found it with small steps like switching over to this limited edition reusable glass water bottle I created. Click the link in my bio to shop."

"Last shoot of the year, can't wait to share this project with you guys," she wrote in the caption, and fans were immediately ecstatic.
