The model, who is married to footballer Peter Crouch, took to her official Instagram page before flaunting her impresive frame.
Stripping to a skimpy bikini, Abbey, 33, oozed sex appeal as she posed up a storm.
Putting her gym-honed abs centre stage, the blonde babe looked catwalk ready – despite giving birth just weeks ago.
Channeling her inner diva, Abbey rocked a pair of larger-than-life shades.
Keen to keep her look as glam as possible, she completed her outfit by draping a thin necklace around her neck.
The former Strictly Come Dancing babe playfully captioned the shot: “Ride or Die,” before adding three palm tree emojis.
Within minutes the post was flooded with messages of adoration.
“Fit” one fan simply praised.
Another added: “Slay bae”.
Meanwhile others flooded the comments section of the post with red-hot fire emojis.
Earlier this week Abbey and Peter confirmed their new son has been named Jack.
Writing in the Daily Mail, the football-ace said: “We have just welcomed our fourth child, Jack, into the family and the wonderful chaos that comes with a new baby means it hasn’t really hit me that I haven’t gone back for pre-season training.
“Life is hectic in a brilliant way.”
