Big Reunion star Jodi starred alongside Ali in the C4 soap in the early noughties and they have remained BFFs ever since.
Jodi played Debbie Dean in Hollyoaks, while Ali played Becca Dean - who was married to Jodi's on-screen brother Jake.
Ensuring a fun day out for Jodi's two-year-old son Koa, the girls headed to the National History Museum in London yesterday (5 October).
Jodi has since shared several snaps taken during their day out, including one of herself cuddling Koa while looking at the dinosaurs.
Commenting on the Instagram photo, Jodi said: "Me and my baby boy and best friend at the National History Museum checking out the dinosaurs!!!"
The trio had caught the train into London and Jodi also posted a cute picture of Ali and Koa snuggled up together.
She added: "Pulling a face with auntie Ali. So excited to be on the train!"
It's been a busy weekend for the girls, as on Saturday night they had attended a charity dinner with another of their former Hollyoaks co-stars - Sarah Jayne Dunn!
The fundraiser was held in aid of cancer charity LAP Research and Sarah - who played Mandy Richardson - posted a snap of herself, Jodi and Ali all dolled up on her Instagram page.
What a blast from the past!
