James Packer’s former fiance Kate Fischer — now known as aged care worker Tziporah Malkah — has penned an open letter to his most recent partner Mariah Carey, advising her how she could win back the billionaire’s love. Malkah, who was in a two-year engagement with Packer until the pair split in 1998, had recently accused the businessman of using her name to keep himself in the press. In the lengthy letter, addressed directly to ‘Dear Mariah’ and published in this week’s edition of New Idea, Malkah said she was sorry to hear the pair had recently parted ways. “My advice to you is, if you really want him back, play the game, let him make the key decisions and you may well live happily ever after as Mariah Carey Packer,” she writes. The former model and actor outlines her own early courtship with Packer in the mid-90s, detailing romantic dates and dinners — and arguments. “Here’s a tip, Mariah,” she writes. “If you want to get him back and he’s having a sulk, just wait a few days and get in touch.” Malkah suggests Carey is “perhaps lucky” she didn’t have to meet James’ late father Kerry Packer, who she describes as “intimidating” with a great temper. As for his mother, Ros: She “isn’t the easiest woman to impress. Did you find that, Mariah?” Malkah also reveals the true reason she and Packer split, saying an endless array of hangers-on in their life meant she struggled to have one-on-one time with her partner during their five years together.
