The Liverpudlian model - who is married to Stoke City striker Peter Crouch - showed off her winter maternity wardrobe as she made her way through Soho, clutching a banana for a healthy post-lunch snack.
Just a few weeks ago Abbey announced she was expecting her second child with her footballer beau, later revealing she was already four months pregnant.
And she clearly wanted the world to catch a glimpse of blossoming bump, leaving her long padded jacket undone while sporting a super-tight LBD complete with a high neckline and thigh-skimming hem.
Warding off the January chills, Abbey covered her pins with black leggings while adding a very glamorous touch with a pair of towering over-the-knee suede boots.
To complete her daytime ensemble, the Strictly Come Dancing winner topped her blonde wavy locks with a fedora hat, toting a quilted Chanel leather handbag under one arm.
Abbey, 28, and Peter, 33, are already parents to Sophia Ruby, born in March 2011. The couple wed three months later in June, in a romantic ceremony held at Stapleford Park Hotel in Leicestershire.
And the starlet has had plenty of other exciting news to celebrate too. Abbey was named Ultimate Style Icon at the Cosmpolitan Ultimate Women of the Year Awards in December, and she recently posed up a storm in sexy lingerie for Ultimo's Christmas campaign.
Meanwhile, Abbey has also launched a nine-piece capsule range of party dresses for Matalan, plus she's been snapped up as the face of Avon's latest fragrance, Cherish.
