And clearly things are still very friendly between the exes, with Watkins telling the Australian Women's Weekly that they've spent the isolation period – along with Wiggles bandmates Anthony Field and Simon Pryce – in lockdown together in order to continue releasing more music together.
She explained that they all felt a responsibility to help "alleviate the fears of children and parents" during this unprecedented period.
"Parents are juggling being a teacher, a chef and a parent," Watkins told the magazine.
"Around the world, we have parents asking, 'please make more content!' and it makes you think we're responsible for providing entertainment at the moment so we'll just keep going."
And Watkins and Gillespie aren't the only famous exes seeing out the COVID-19 pandemic under the same roof.
In April, eyebrows were raised when it was revealed Demi Moore was self-quarantining with her ex-husband, Bruce Willis, and their three grown-up daughters in their Idaho home.
To make the situation more unusual: Willis' wife of 11 years Emma Heming and their two daughters Mabel, eight, and Evelyn, five, were not present, and were instead 1500km south of Idaho in Los Angeles.
In an interview released shortly afterwards, Scout Willis explained the family's decision.
"It's been so funny because to me they're just like my super f***ing weird parents but to everyone else, they're at this different level," Scout, 28, said on the Dopey podcast.
"It's actually been really cool. My stepmum was supposed to come up here with my little sisters but my younger sister, who is now about to be (6) years old, at a park, had never gotten the talk about not f***ing with hypodermic needles that she found, so she actually tried to poke her shoe with it and poked her foot.
"So my stepmum had to be in LA waiting to get the results from taking her to the doctor so my dad came up here and then travel got crazy so my stepmum stayed in LA with my little sisters."
Scout said it had been a treat reconnecting with her parents, who've remained friends since splitting two decades ago and through Moore's eight-year marriage to actor Ashton Kutcher, which ended in 2013.
"It's been really funny to have both of my parents in the house where they raised us, which has been really cute. They're both such nerdy, adorable, '90s parents in a small town where they chose to have their kids and not be in LA. It's been pretty cute."
