Previously speaking to Now To Love in April, Carly advised loved-up couples to up the ante on their sex life to pass the time during coronavirus restrictions and joked there might soon be a few babies on the way.
"Increase the sex," she laughed.
"That's what everyone is telling me, who are in couples - that they're just having sex because they're bored. There may be a baby boom in nine months' time."
Carly shot to fame as a bride on Married At First Sight in 2018, where she was matched with ice-cream businessman Justin Fischer.
Their marriage was short-lived and Carly then struck up a romance with co-star Troy Delmege before finding love with her now boyfriend Neil.
Carly now hosts a dating podcast on Nova.
