Kelly Clarkson can't wait to be a mama, for a lot of heartwarming reasons. But one is more immediate than the others: The sooner she's done being pregnant, the sooner her endless morning sickness will go away.
"I don't know why they call it morning sickness — that's my big joke right now," she told TODAY's Savannah Guthrie on Monday while in the studio to chat and sing "Underneath the Tree" from her first Christmas album, "Wrapped in Red."
"'Cause it's like all day and all night," she continued. "I'm just looking forward to the second trimester!"
Clarkson said she and husband Brandon Blackstock (the pair wed Oct. 20) were "dying to tell people" the joyous news, but had wanted to wait until the pregnancy was a little farther along. But the sickness outed her earlier than planned, since she was too ill to perform at times.
"I had to cancel something because I'd been so ill, so I didn't want people to think I was canceling (because) I was lazy or something, so we just told people. But we had a really good reason," she said.
So, girl or boy? Clarkson doesn't know yet, but has her suspicions that it's a feisty gal. "She's killing me," laughed Clarkson. "Of course it's a girl, causing the trouble."
Clarkson is already a stepmom to Blackstock's two children from a prior marriage.
Meanwhile, when the singer is able to take her mind off of the baby for a moment, she's concentrating on both the holiday album and her upcoming NBC special, "Kelly Clarkson's Cautionary Christmas Music Tale." The special will be a comedic, but also musical, tale on a traditional Christmas morality story, and will feature songs from "Red" and guest stars including William Shatner and TODAY's Matt Lauer.
As for her holiday album, Clarkson says she's happy she could be "a little more cheesy" with it than she normally is with her recordings. She even included a song she wrote for her husband, called "Brandon's Song."
"In my career ... everybody's always like, 'Are you pop, are you country, are you rock, what are you?' I think that's what's cool about the Christmas record is I don't have to pick. ... There's just a little bit of everything on it," she said. "I've been making this CD in my head for years."
"Kelly Clarkson's Cautionary Christmas Music Tale" will air on NBC on Dec. 11 at 10 p.m. "Wrapped in Red" is available in stores and online.
