Shane Warne’s ex-wife Simone Callahan shows how NOT to wear a face mask

Whoops! Shane Warne’s ex-wife Simone Callahan shows how NOT to wear a face mask as she walks her dog in coronavirus-stricken Melbourne

Someone needs to tell Simone Callahan how to wear a face mask properly.

The 49-year-old ex-wife of cricket legend Shane Warne took her dog for a walk near her home in Melbourne on Wednesday.

And while she was wearing a mask – which all Victorians have been ordered to do as the state battles a second wave of coronavirus – she made an embarrassing gaffe by failing to cover her face properly. 

Fail! On Thursday, Shane Warne’s former wife Simone Callahan (pictured)  popped out to walk her dog in Melbourne wearing her face mask under her nose rendering it ineffective 

The former model and yoga enthusiast only covered her mouth with the mask, leaving her nose uncovered. 

This method renders the mask completely ineffective because respiratory droplets are spread by coughing and sneezing. 

Simone lives in Melbourne, where it is compulsory to wear a mask when leaving the house unless you have a medical exemption or are under the age of 12.

There is no medical exemption that permits somebody to wear a mask that only covers the mouth. 

Whoops: Face masks are not effective if worn below the nose, because respiratory droplets can also be spread by coughing and sneezing and the nasal secretions in people suffering from COVID-19 have tested positive for carrying the virus

Meanwhile, Simone kept things casual while walking her Pomeranian with a friend.

The mother of three showed off her toned physique in tights and a Gap sweater, which she paired with leg warmers and pink sneakers.

She appeared to go makeup free during her permitted daily exercise session.

Simone took off her mask once she returned home.

Meanwhile, Simone and Shane’s son, Jackson, is getting set to make his TV debut.

The 20-year-old is currently filming Channel Seven’s new reality show SAS: Who Dares Wins in the NSW Snowy Mountains.

Based on the British format, the program will put stars through their paces as they attempt to pass the selection process to join the Army’s elite Special Air Service.

It boasts the biggest celebrity cast ever assembled for an Australian reality series, including PR queen Roxy Jacenko and Ironwoman Candice Warner.
