"Be like the Czech Republic," says Olivia Newton-John in regards to making and wearing face masks

“This is of major importance for us all to know,” the singer wrote on Instagram.

“We have been told we don’t need masks because health workers need them desperately and there aren’t enough for the general public too! Please pass this video on – let’s be creative and make our own – like the Czech Republic has – and thank you to #Masks4All for sending this out to the world. We can flatten our curve too!!”

Olivia Newton-John rose to fame with a string of #1 hits in Australia in the mid-1970s, but her career really took off after starring alongside John Travolta in the 1978 film adaptation of Grease.

The coronavirus is of special concern for the 71-year-old singer, who is currently fighting stage 4 breast cancer; contracting COVID-19 could have fatal consequences.

Newton-John previously battled back from breast cancer twice before, in 1992 and 2013.
