The mother of six was spotted on the beach in a bikini looking incredibly svelte and insiders tell New Idea Nicole is worried about the 48-year-old’s extreme weight loss.
“Antonia has always been really health conscious and fit, and she’s always on her feet, being a mum of six,” a source reveals.
“But Nicole’s starting to worry that she’s taken it all too far, and that she needs to relax her health and exercise regime a little bit and slow down,” they add.
According to the source, Nicole is very protective of her sister particularly since Antonia’s first husband Angus Hawley’s death in 2015, and also the death their father, Antony Kidman the year prior.
“Nicole knows that it’s been a rough few years for Antonia with their father passing away and of course Angus dying so suddenly. Nicole has always been there for her and is worried that all the stress and heartache – as well as her busy life – are taking their toll on Antonia.”
Indeed, Antonia has a lot on her plate and a lot of challenges raising her large brood.
She has four children from her marriage to Angus: Lucia, 20, Hamish, 17, James, 15, and Sybella, 11.
With new husband Craig Marran, who she married in 2010, Antonia has two children – Nicholas, 8, and Alexander, 6.
Antonia and her family live in Singapore, where her husband’s business is based. She has previously admitted that she keeps herself sane by swimming as her husband is travelling a lot and she’s home alone with the children.
“When I swim, I get time to myself and so I get to think a lot,” Antonia told 9Honey.
“I like to have purpose, that’s why I do so many things. It feeds me, it feeds my sense of self.”
