Tziporah Malkah looks set to unveil a bold new look on A Current Affair.

The 90s model formerly known as Kate Fischer appears in a new promo for the show announcing she's back after a dramatic makeover.

"I'm back and wait till you see me this time," she says in the clip.

The video shows 45-year-old Malkah, who was once engaged to James Packer, sporting bright new orange hair and a toned, slim figure as she lies in a floral bikini on the beach.

It also promises a "raw and uncovered" interview.

Earlier this year, Malkah revealed to New Idea she had lost more than 50 kilograms with the help of a hypnotist and a personal trainer.

When she appeared on I'm A Celebrity … Get Me Out Of Here! in 2017 she had weighed more than 120kg and said she was in "bad shape, mentally and physically".

"I'm down 10 dress sizes — from 24 to 14. This is the lightest I've been since I was 35 — more than a decade," she told New Idea.

Malkah's appearance on the reality television show marked her return to the spotlight after a decade of staying away from public life.

She was one of Australia's most successful models during the 1990s and appeared on the cover of numerous magazines and overseas campaigns.
