The Good Morning Britain team already have seven children between them - Susanna has three sons, Ben Shepard has two sons and Sean has a son and a daughter.
Former Sky presenter Charlotte, 39, admitted that keeping her pregnancy a secret from her co-hosts was a struggle as she feared her cravings for biscuits and chocolates would give her away!
Charlotte's first baby with her husband Mark Herbert is due in February 2015.
