Roxy Jacenko has opened the lid on her marriage to Oliver Curtis amid rumours that their relationship is on the rocks.

The couple, who have been married for over 13 years, are rarely seen together in public, which often prompts speculation about the state of the marriage.

And with Roxy spending half her time in Sydney and her investment banker husband staying in Singapore, it's no surprise why split rumours have run rampant.

However, the PR maven put all whispers in the Sydney sphere to rest, telling the Daily Telegraph that her relationship is on firm ground.

Describing her husband as 'kind', 'helpful' and her 'best friend', Roxy added that he's also much better in the parental department than she is.

'I am not hands on, he is very hands on,' she said of her hubby.

Roxy then addressed their public appearances, saying: 'I have just never been that lovey, dovey… I don’t need to hold anyone’s hand walking down the street.' 

The couple have no doubt had their low points, such as when Roxy was spotted kissing another man while Oliver was serving time for insider trading, a move she admitted was really 'stupid'. 

Speculation that the couple have separated rose after Roxy moved back to Australia from Curtis' home-base in Singapore at the end of 2024.

Roxy is believed to be spending one week a month in Sydney.

Oliver and Roxy married in 2012, and are parents to daughter Pixie, 13, and son, Hunter, 10. 

She maintained that Oliver had been good to her over the span of their relationship.

In a final gush about her hubby, Roxy said she was lucky to have him.

'Not many people could put up with me – or my chicken dinner,' she laughed.

The dinners she's referring to, comprised of grilled chicken and a Greek salad - are part of an extreme health regimen that the PR queen maintains.

The strict diet sees Roxy only eat one meal a day in order to maintain her goal weight of just 50.9kg. 

She told Daily Mail Australia she also does daily contrast therapy, which involves taking baths in warm and cold water from Monday to Friday.

This method is believed to help to improve blood circulation throughout your body.

On top of that, she does 40 minutes in an infra-red sauna each day before completing a 45-minute workout on the treadmill at speed 6 and rolling hills, as well as low-weight exercises.

'I don't do breakfast or lunch, instead I do dinner at 7pm each day which is focused on protein only and salad,' she explained.
