The model, 29, flaunted her expectant figure this weekend (28 March) in a strappy little number at the prestigious event - known to be the world's richest race.
And the former Strictly winner certainly didn't look out of place at the glam affair in the United Arab Emirates.
Attending with her footballer husband Peter Crouch, Abbey stunned in a black summer dress with floral pattern which she teamed with cat eye sunglasses and khaki heels.
Posing in a picture with Splash star Danielle Lloyd, Abbey looks every inch the yummy mummy.
Posting the picture on Instagram, Danielle - who also looks gorgeous in a green minidress and cream feathered hat - wrote: "Dubai World Cup fun with this perfect couple abbeyclancyofficial and Peter can't wait for baby number 2."
Danielle also shared a photo of two of her sons playing with Abbey's daughter Sophia, who is four.
She wrote: "My babies loving dubai life with princess Sophia abbeyclancyofficial #bestfriends."
Abbey and Peter are expecting the birth of their second child in May.
