The former model married the billionaire media tycoon in 2016 but insisted it isn't important to be "friends" with an ex.
"Not all exes you want to be friends with, do you? Some people aren't friendly. But I think when you have children with someone it's important to be friendly," she told Britain's Vogue magazine.
"Rupert, we were married six-and-a-half years and no children, and so, you know."
Asked if she sees Murdoch, Hall shook her head and said: "I haven't seen him in a couple of years. Since the divorce."
The divorce was the fourth for Murdoch, who married Hall in London in March 2016.
By contrast, Hall has a good relationship with first husband Mick Jagger - the father of her children Elizabeth, 42, James, 40, Georgia, 34, and 29-year-old Gabriel. Jagger is a regular visitor to her home, along with partner Melanie Hamrick and their eight-year-old son Deveraux.
"He comes out here quite a bit, Sunday lunch, him and Mel and their son, Dev. They're so sweet," she said.
Hall, who turns 70 in July, praised the Rolling Stones frontman - who has eight children with five women - for keeping their extended family on good terms.
"Mick's a great diplomat. All the kids love each other. All the mothers of the kids love each other. It's just odd, isn't it? Just worked out that way."
Hall says going through a divorce is "always traumatic" but is philosophical.
"'What will be, will be,' that's my saying. And it really works. If it's meant for me, it's gonna happen. If it's not?"Â
Hall said she isn't interested in looking for love again.
"I sometimes see people and think, 'He's cute', but I kind of can't be bothered."
