Field said it had been "a very long and difficult path to get here".
"Family comes in all forms, and this little lady, who is biologically ours, was carried by an incredible surrogate mother, to whom we will be eternally grateful," she added.
"We are over the moon to have this beautiful baby girl in our lives and so blessed that we live in a world which makes this possible."
The couple are already parents to daughter Theodora 'Teddy' Rose, aged five; and son Charlton 'Charlie' Valentine, aged three. They asked for their privacy to be respected.
The new series of The X Factor continues on Virgin Media One and ITV this weekend.
