The yummy mummy-to-be then revealed that she and boyfriend Dan Osborne - who have been dogged by breakup rumours since the EastEnders star announced her pregnancy - actually teamed up to get a joint birthday present for the little boy.
And they decided to go all out with an awesome motorised 4x4 for little kids.
Posting a video of John driving around in his birthday gift, Jacqueline wrote: "John's birthday gift from me and Daniel."
The post comes shortly after Dan Osborne, 23, opened up about his relationship with the real-life Lauren Branning.
He said: "Hopefully I'm with someone who knows enough about me to trust me.
"Is Jacqueline the one? It's hard to say but I'd like to think so."

While Jac and Dan are reported to have had a number of fallings out in recent weeks after it was revealed he'd sent a naked picture of himself to his co-star Georgia Kousoulou, the Essex lad insists this couldn't be further from the truth.
He shared: "Having everyone watching you does add pressure.
"My relationship off screen does limit my storylines, but I'm glad because I don't want my role on the show to be all about dating."
The couple are expecting their baby boy or girl early next year, around the same time that Lucy Beale's killer will be revealed in EastEnders.
We're so excited to meet their little bundle of joy - with parents as generous as these, he or she is definitely going to be the most spoiled baby in town!
