The Paige Spiranac rival showed off her bum while wearing a skimpy green two-piece in a pool of water.
Katie Sigmond looked incredible for the mud-splattered ʙικιɴι belfie
She was smothered in muck for the snap, while looking back at the camera with sunglᴀsses on her head.
Katie is on South Pacific islands of Fiji at present, taking a holiday break with a group of friends.
And she has stepped up her usual saucy content, including the latest images on social media.
She captioned the post with: “straight out the mud” with palm tree emoji.
One said: “You look gorgeous.”
Another added: “H๏τtt!”
A fan replied: “My profession is all of a sudden mud cleaner…”
Yesterday, Katie showed off her stunning figure in a tiny black ʙικιɴι on a boat.
The 20-year-old was spotted leaping off the yacht, to join pals already in the sea.
