The "Something In the Water" singer announced her pregnancy with husband Mike Fisher in September, and the two are patiently awaiting their baby boy.
Carrie talked to ET last month about how her vegan diet has been affected by her pregnancy, and made it clear that she's staying committed to her healthy ways.
"I think because I am pregnant, I allow myself to eat things I normally don't eat," she said. "Now I'm pregnant, it's like, I can't just order steamed broccoli. That's not going to cut it. I've modified a little bit, but I think I've stayed pretty normal."
