Tziporah Malkah has fans worried after the ex-model went on an Instagram posting spree on Monday.
WATCH: Tziporah Malkah shares bizarre video wearing lingerie
Tziporah posted a number of strange images and selfies, and at one point, the 45-year-old even posed completely nude for a bedroom pic.
In the photo, Tziporah, who was once known as Katie Fischer, is seen sat on her bed surrounded by stuffed soft toys and pillows as she snapped herself in the mirrored wardrobes opposite her bed.

Her bizarre photos then continued as she shared a stream of pics of herself wearing black lace underwear.


“My dodgy ole bod,” she wrote in one caption, and tagged a PR company.
And her odd posts continued.
In hours that followed, Tziporah shared an array of unusual selfies looking vacantly at the camera.
Other posts consisted of Tziporah’s old modelling photos and even an image of a cherry-inspired toilet brush.
Tziporah’s unusual social media activity comes after she recently showed off her 50kg weight loss on A Current Affair.
Speaking on the show in October she told A Current Affair reporter Brady Halls: “[The] mental anguish from all the stresses of life are just not there anymore… And I think that’s probably the greatest gift.”
Tziporah then broke down in tears, overwhelmed by how far she has come.
