CARRIE UNDERWOOD'S CHRISTMAS BEFORE THE BABY'S BIRTH

Carrie Underwood is getting ready to celebrate Christmas with her son Isaiah, 3, and her husband Mike Fisher, and it will be their last Festive Season as a trio.

The 35-year-old Underwood is expecting the couple's second child, another boy, but her son Isaiah seems to be less than impressed by the prospect of sharing mom.

“[Isaiah] told me recently that when the new baby comes that Daddy could have that baby and then he could be mine.”

Underwood cautiously announced her pregnancy on Instagram in August when she was already 4 months along.

In September, Underwood revealed that she had gone through a nightmarish three miscarriages over the last two years, and the successful pregnancy had put her "over the moon."
