"I'm familiar with all day sickness," she joked, before getting serious for a moment. "It’s pretty bad. I have to get IVs and fluids, I get so dehydrated. It's really bad."

But in the end, Clarkson says it will all be worthwhile -- and she has a pretty hilarious take on the miracle of childbirth. "We pop out magical unicorns," she teased.

Clarkson made headlines when she unexpectedly revealed her second pregnancy live on stage at Staples Center in Los Angeles. The singer broke down in tears while singing her song "Piece by Piece."

"I couldn’t get through it and I was crying so hard, I thought these people were going to think I’m on drugs," she explained. "They’re going to think I'm going to lose it like a crazy person. I was like, 'I gotta explain.'"

"Piece by Piece" is featured on her album of the same name, co-written by Clarkson about her strained relationship with her father and her marriage to Brandon Blackstock.

"My husband came into my life and he's the complete opposite of how my father was," she said. "He was present, he wins for being around."

The couple wed in October 2013 and welcomed their first child together, a daughter named River Rose, in June 2014. Clarkson is also now a stepmother to Blackstock's two children from a previous marriage.

In her interview on Wednesday, Clarkson also revealed her surprising career aspirations as a young singer.

"My initial goal actually even when I was little, wasn't to be the frontrunner. I wanted to be a backup singer," she revealed. "I am so happy we have Madonna, and Britney and Beyonce -- y'all just live it up. I wanna be, like, right underneath."

For now, Clarkson is focused on her role as mom and welcoming baby number two. See her adorable gender reveal announcement in the video below.
