Naomi looked effortlessly chic in a pink shirt with a white cardigan, with her hair pulled back into a ponytail.

Rebecca, who is the wife of Mentalist star Simon Baker, wore a grey ribbed cardigan as she joined her famous friends in pointing to the camera.

The trio, appear to be in their late teens to early twenties in the image, but barely seemed to have aged a day.

The pair first met at high school while attending North Sydney Girls’ High School.
