The pregnant model shared an image to Twitter on Tuesday (7 April) showing herself flaunting her baby bump for the camera.
Her caption read: "Just over six weeks to go and counting."
Abbey, 29, and footballer husband Peter Crouch, 34, are already parents to daughter Sophia Ruby, who turned four in March.
They announced a second baby was on the way in December, with Abbey tweeting: " "Super excited to announce Pete and I are expecting our second baby! We couldn't be happier."
While we reckon Abbey has looked INCREDIBLE throughout her pregnancy, she hasn't been so sure, telling The Times: "One part of your brain is going, 'Oh my God, I'm so blessed, it's a miracle', and the other half is going, 'I can't bear this, I'm so fat, I'm ugly, I've got headaches, I've got spots, I feel sick..."
"Pete's not too happy with me moaning every two seconds [and] the perks... the big boobs and that - he can't go anywhere near because they're too painful!"
The couple have decided not to learn the sex of their second child before the birth.
Celeb maternity fashion!
