Kelly Clarkson's Gets in The Holiday Spirit With Underneath The Tree

This is the first child for Clarkson, who married country singer/actress Reba McEntire's stepson last October at Blackberry Farms in Tennessee.

When Clarkson visited New York's Elvis Duran & The Morning Show that month, she spoke about her future plans for a baby and accurately predicted the gender. "I want babies like right off the bat," she said. "My first child will be a girl. I know it in my soul.

Two months later, Clarkson visited The Ellen DeGeneres show in December, and revealed that her first pregnancy wasn't going as smoothly as a woman would hope.

"I vomit a good dozen times a day," the singer said. "I'm not even kidding, it's so bad. It's so bad. It's, like, so gross."

The 32-year-old, who wore a long red gown to the show, went on to say the pregnancy hasn't changed her physical attributes for the better, the way many claimed it would.

"Everybody tells you you glow and your hair is pretty and your nails are pretty," she joked. "That is total crap. My nails are short, my hair still falls out, it's not all lush and beautiful, and I have no glow, unless it's something left over from a bathroom trip. It's horrible."
