Addressing the front-page story on her KIIS FM breakfast show, the 45-year-old admitted she had made a mistake and felt ‘really stupid’ for forgetting her mask. 

Her co-host Kyle Sandilands started the broadcast at 6am by rattling off the negative headlines about Jackie, who was clearly mortified.

She said she found it particularly embarrassing because she had previously spoken of the importance of wearing masks and social distancing during the pandemic. 

‘It’s my fault, I feel really stupid,’ Jackie confessed.

The mother-of-one explained that she had been rushing from her hotel to the set, and only realised on the drive over that she’d forgotten her mask. 

She said: ‘I was coming from my hotel room… and we’re always running late with hair and makeup, and then we quickly packed everything up and we got in the car.

‘It’s only a two-minute drive, and on my way I thought, “Oh my gosh, I’ve forgotten my mask.” No excuse [but] I got out of my car and they gave me a mask.’

Jackie explained that the photo of her without a mask had been taken in the split second when she was dashing from her car to the set.

She concluded: ‘It’s stupid. I was in a rush. I forgot it, and I’m sorry.’ 

Extreme measures: Meanwhile on Tuesday, Jackie wore a mask and a clear shield while doing her radio show from a KIIS studio in Melbourne. She said she's allowed to just wear the shield once her hair and makeup is done on set
