Tziporah Malkah has reportedly lost 19 kilograms and it's all down to love.
A "close friend" of the former model revealed to Woman's Day, her weight loss is because of healthier eating and just generally being happier after dating her teenage sweetheart Guy Vasey.
"I call it the love diet," the source told the magazine. "And it's really sweet that her boyfriend has been supporting her all the way."
The insider also revealed to the publication the 44-year-old's boyfriend has "been training her and walking with her each day to encourage her".
Tziporah - formerly known as Kate Fischer - lost an impressive 14 kilos earlier this year while on I'm A Celebrity... Get Me Out Of Here! but unfortunately put the weight back on once returning from the jungle.
However, it seems the "love diet" has put her back on track.
Tziporah was previously in a highly publicised relationship with Australian billionaire James Packer in the 1990s.
After their break up she retreated from the spotlight, moving to the United States and legally changing her name.
