"It is with great excitement that Stuart and I announce we are expecting our first child," Ritchie announced on the social media site.
"We can assure you any secrecy up to this moment has been nothing more than us protecting what is most sacred - a new life that was far from reaching its 12 week milestone.
"Thank you to all who have respected our privacy over these past weeks allowing us the privilege every couple deserves - to share the wonderful news ourselves," she added.
"It really is such a special time for us and we couldn't be happier!"
