Celeb followers of the Sydney-based mum-of-one were quick to express their delight at the photo of the young Jackie, who looks to be a teenager in the snap.
"LOVE IT 😍 At least you had two eyebrows. My “friend” only had one 😳😳😂" said Australian TV presenter Sally Obermeder.
While MAFS Jules Robinson also blamed Pammy for her lack of eyebrows: "Me too !!! Complete blame !! X"
"This is awesome! Love it baby.😍" commented Jackie Gillies.
The official Instagram account for the most popular radio show in Australia, the Kyle and Jackie O show also shared the hilarious - and less-than-beautiful - snap.
No word yet from best friend and co-host, Kyle Sandilands, on his thoughts on the throwback photo, but we can safely assume the Australian shock-jock will have plenty to say..it wouldn't be the first time!
