Holly Valance was cut off during a live interview on GB News after she used a slur about people with learning disabilities during a debate about the pandemic.
The singer was speaking after Apple Music briefly banned her 'anti-woke' song Kiss Kiss (XX) My A**e, which is a soundtrack to Pauline Hanson's new film, A Super Progressive Movie.
Valance told host Josh Howie on Free Speech Nation on Monday: 'During Covid was the big like tester to see.. like the retard meter. And Australia was quite high on that.'
Howie quickly apologised for her use of the term 'retard' and said: 'Sorry for using that word, but that's okay, but... I think some people unfortunately might be offended.'
Unapologetic, Valance said: 'Hey, are we not Free Speech Nation over here? Where am I?'.
Howie replied: 'You're right, you've got me there. We are Free Speech Nation, apart from that one word.'
Reacting to the moment, one viewer wrote on X: 'Holly Valance really said filter off and hasn't looked back since. Dropping that on GB News before the watershed is the ultimate middle finger to the polite political establishment.
'She’s leaning fully into the Reform UK energy, making it clear she doesn't care about being cancelled because her base is already locked In.
'Whether you love it or hate it, she’s mastered the art of getting the whole internet talking about her on a Monday morning. The Kiss Kiss era feels like a lifetime ago!'
Another wrote: 'No need for it, as you well know. Poor choice of word'. And a third said: 'Hate the word it’s offensive and no need to say it.'
A fourth wrote: 'It’s used against disabled people and those with learning disabilities on a daily basis. Which is so wrong. There is no need to use the word.'
During the interview, Valance spoke about her song being banned briefly from Apple Music.
The track was released on Australia Day and reached No.1 on the Apple Music iTunes best-selling songs chart – soaring ahead of tracks by Keli Holliday and Harry Styles.
It was later removed from the platform after it briefly overtook Olivia Dean's Triple J Hottest 100-winning song, Man I Need, before being reinstated following a backlash.
She said: 'If it was like a Trump-bashing right left-wing, Farage-bashing, song that someone on the left side of politics made, then it would have been fine. It would have been no issues because the right don't tend to have toddler tantrums.
'We never received any email officially from iTunes or Apple or anybody. So I was like, "what's going on?"'
The song is a reworked version of Valance's 2002 hit Kiss Kiss and features lyrics taking aim at trans issues, 'snowflakes' and 'cancel culture'.
Lyrics of the song include: 'MWAH You will respect my pronouns / Not all ladies have ovaries, some have a penis / They say that I'm a he but I'm a she / 'Cause I gotta V and not a D.
'And I don't care what people say / I'll never be a him, a them or they / 'Cause I'm a real biological woman / A real biological woman.'
When the song was released, Australian politician Hanson said: 'Wouldn't the ABC have a heart attack knowing they had to play this track.'
Despite its popularity in downloads, the song only managed around 50,000 streams on Spotify, failed to chart on Australia's major streaming services, and did not enter the country's official rankings.
The song received plenty of criticism for being transphobic and attacking minority groups.
Despite this, some social media users were quick to ask why they couldn't access the tune.
'Who gave Apple the go ahead to tell us what music we could download?' one Aussie wrote while another added: 'I'm so buying it.'
Valance, who is now based in the UK, has in recent years become a vocal supporter of conservative politics and has publicly backed Nigel Farage's Reform UK party.
The One Nation leader's film is about four 'progressives' who find themselves in the 'real-world' led by Hanson after their 'rainbow malfunctions'.
The film has a 4.8 rating on renowned website IMDb, and that average figure comes from users mainly rating it either 1/10 or 10/10.
The movie's release comes amid skyrocketing support for One Nation among Australian voters, tying it with the Coalition for the first time.
