Abbey, accompanied by her even-skinnier fiance, Peter Crouch, wowed onlookers with her blue and white abstract print barely-there ensemble at the service in Liverpool.
Peter and Abbey became proud parents to Sophia Ruby back in March, and body-conscious Abbey was spotted striding out in skinny jeans just days after her daughter's birth.
Rumour has it the couple are due to tie the knot next month - so could this be the reason behind her super-speedy weight loss?
Do you think Abbey has shed the baby weight (was there ever any?) too soon? Or is her age and busy lifestyle the secret behind her pinging back into shape so quickly?
