The pair have teamed up with Palmolive, with the mum posting a cute video of her mini-me.
Alongside the footage, she wrote, "Teenager in two weeks!!! 😱 Self care is an important part of growing up!"
Fans were gobsmacked by how quickly the time had passed, with one saying: "No way... seems like only yesterday you and baby Mia were at the Logies in matching dresses...wow has time flown."
Another commented: "Grown up so quickly I hope she is happy and enjoying life."
Mia is big sister to Cruz, nine, and Ava, eight.
