The stunning model, 28, is expecting her second child with footballer husband Peter Crouch, and showed off her blossoming belly for the first time on Boxing Day.
Posting a picture on her official Instagram account, Abbey can be seen pulling her top up and displaying her newly-rounded tum to the camera.
She joked: "Belly's gonna get ya!!!"
Her engorged tum could be all baby, or a little bit of post-Christmas dinner bloat too... And we know ALL about that!
Abbey can clearly be seen laughing in the picture, as she lies beside a man who also has a little, ahem, pot belly - sorry whoever you are!
Responding to a message from a follower who didn't know she was pregnant, Abbey tells her: "Yes [I'm pregnant]. Four months, so excited xx."
And, if any of you needed any reminding, Abbey usually has a tummy that is enviably flatter than a pancake!
Former Strictly champion Abbey announced she was expecting another baby last week.
She wrote: "Super excited to announce me and Pete are expecting our second baby. We couldn't be happier."
Stoke City striker Peter added shortly after: "We are expecting baby no 2 woo hoo."
The couple tied the knot in a romantic ceremony at Stapleford Park Hotel in Leicestershire in June 2011.
They are already parents to three-year-old daughter Sophia Ruby.
