Some families look related but don't look alike, and then on the other end of the spectrum, some families look like the physical manifestation of Groundhog Day.
Radio and TV personality Jackie O falls into the twinning camp with her daughter, Kitty, nine because of their remarkable likeness.
The most recent snap Jackie O posted of her daughter shows how grown up Kitty has become seemingly overnight.
Jackie O really copied and pasted her looks when she gave birth to Kitty because they have the same features and face shape, and of course, they share Jackie's iconic golden locks.
The doting mother gushed in the caption, "My angel, my everything ❤️❤️❤️❤️❤️❤️❤️❤️❤️."
A choir of Jackie O's famous friends took to her Instagram comments to gush over the pretty picture.
PR expert Roxy Jacenko wrote, "Beautiful girls ❤️❤️❤", while fellow radio personality Fifi Box commented, "So beautiful you two 💕🥰💕🥰💕."
Dannii Minogue also commented, "Miss you guys."
The girls are clearly well-loved by the industry but whose heart doesn't melt looking at this loving mother and daughter duo?
Kitty was born in 2010, and after growing up with a mum cemented in the Australian showbiz scene, she may decide to follow in her footsteps.
When Jackie was filming The Masked Singer, she revealed to TV Week that the job enamoured her daughter.
"She was loving it and wanted to come every day," Jackie told TV WEEK, "It was the first time, I think, where she was like, 'Wow, you have a really cool job, Mum!'"
Jackie separated from Kitty's father, Lee Henderson, in 2018, but the split was amicable, and they have prioritised their daughter's happiness above all.
Jackie made that priority clear when she released a statement about her divorce to clear up any speculation.
"After 18 years together, we have made the decision to separate. We do so amicably, sharing many incredible memories and remaining best friends," the KIIS FM presenter confirmed at the time.
"Our focus for this next chapter is of course our wonderful daughter and continuing to provide her love and happiness, together."
