Samantha Armytage has opened up about the moment that she realised she no longer cared about what people thought of her in her new column for Stellar.

The Sunrise co-host explained the specific moment that she decided that she would no longer worry about what people thought of her.

It was over a Christmas tree.

She explained that she was “mercilessly mocked” for putting her tree up in November and realised that if people complained about her – a complete stranger – getting into the festive spirit early, they were going to complain regardless.

“Girls are becoming boys and boys are becoming girls. And we’ve got no water and we can’t afford electricity,” the 43-year-old wrote.

“Children don’t know how to play anymore and no-one can sleep because we’re all so stressed from reading banal stuff on social media all night.

“Everything is topsy-turvy right now. So I asked myself, ‘What sort of person in this cray-cray world could possibly judge me for putting up the Christmas tree a month early?’”

Armytage made a point to not let judgements impact her this year and let her "freak flag fly".

“You see, I’ve discovered the meaning of life and I’m now on the verge of greatness. Because I really don’t care what people think of me anymore,” she concluded.

This isn’t the first time that she’s called out people online, especially after people were body-shaming her after her 10kg weight loss.

“Do you know what? My weight is already scrutinised," Armytage told The Australian Women’s Weekly. 

"I understand there will be more scrutiny that comes with this … but the paparazzi are always already trying to take pictures where there is a fat roll showing.”
