"On the way to the dentist, where I will get drilled," the women sing in perfect harmony.

"On the way to the dentist, I'd rather have a pill," they continue.

"What we do when we do anything. #sing @therealonj," Chloe captioned the post.

Fans were thrilled with the glimpse into the daily life of the duo.

"So lovely to hear you both sing together. Please post more songs together to brighten the spirits of those in Melbourne in lockdown," a second asked.

"Beautiful mother-daughter duo and harmonies," a third said.

The pair are incredibly close, with Chloe saying that seeing her mum is "good medicine".

"I love seeing my mum. It's good medicine. When I don't see my mum for a long time, it's like I feel ill," Chloe told The Australian Women's Weekly last year.

"When I'm with her, it feels like all is right with the world. She makes me feel safe."
