Karl’s wife Cassandra pens open letter amid split reports

Cassandra Thorburn has addressed her reported split from Today show host Karl Stefanovic, in a passionate open letter published by Popsugar.

In the essay, titled Dear Working Mums, the 44-year-old seemingly describes the break-up as "one of the hardest times of mine and my children's lives."

Cassandra, who is mum to Jackson, 16, Ava, 11 and River, 10, also went on to slam women for being unsupportive of her during her difficult time.

"It's such a shame that the biggest critics of women seem to be other women," she wrote. "Such a damn shame."

The mum-of-three writes that she garnered criticism from some publications who "suggested" she was boozed up when she posted a Facebook message earlier this week of a celebratory glass of red wine.

"If you did read the article I referenced earlier, I can guarantee you I did not write the Facebook post after drinking a bottle of red, as was suggested," she wrote. "That was my first glass in the photo.

"I'd just poured it, to celebrate something that played a huge role in my life for so long. There was no malice intended and I certainly didn't expect to be picked to pieces for it."

She added: "The media showed no interest in this stay-at-home mum for 11 years, so kicking me now when I'm going through one of the hardest times of mine and my children's lives seems very cruel indeed."

The Facebook post that Cassandra's referring to, praised the successful ratings of her husband's TV gig, the Today Show, and hinted that it's success has cost her greatly.

"Apparently Today Show finally won a year. This took a huge toll on my family and I, and I’m congratulating myself today for all the effort that went into making that [ratings] happen," she captioned on the Facebook post.

"The suggestions, the story ideas, the constant counselling of questions for years.

She continued: "I’m giving myself a pat on the back tonight, as I know many people will also know how much effort I put into it.

"Found a lovely tipple to cheers myself. Thanks for the red Sharon Finnigan SF Celebrity Management," she added, referencing Karl's manager.

Karl himself has previously spoken about how Cassandra sacrificed her own career so she could raise their three children.

In 2015, he said: "She gave up a promising career... and I'm forever thankful and tremendously appreciative of that."
