Posting on her Twitter page on Friday (March 16), Duff expressed her impatience to give birth as well as her frustration with her ever-increasing size.
"Ok! no joke.. When i get up my massively pregnant morning walk looks like a "walker" from "the walking dead" #cmooooon BABY (sic)," she wrote.
In February, Duff posted a photograph of herself and Comrie on Twitter, displaying her baby bump at its largest.
Duff has confessed that she is a little afraid of motherhood, saying: "Anything that's unknown is scary to us, and I'm definitely a little afraid. It's not something you want to mess up and it's not something to take lightly."
