Kelly Clarkson is happy with keeping her family a family of six.

The 34-year-old singer and former "American Idol" winner revealed on Tuesday's episode of "The Ellen DeGeneres Show" that she doesn't want any more children because of her already-hectic days.

"We have four because I married into two," she said of husband Brandon Blackstock's children from his previous marriage.

"I already have days where I, like, cry, so we don't need any more kids. It's a lot."

Clarkson and Blackstock married in Walland, Tenn., in 2013.

The couple share 2-year-old daughter River and 5-month-old son Remy, along with Blackstock's 15-year-old daughter, Savannah, and 9-year-old son, Seth.

"There is a giant difference between one kid and two, and then there's an even bigger one -- we have two older ones as well," the singer told E! News the same day.

"A lot of times we'll have four kids in one house, so that's a lot of kids."

"Unless someone dies and gives us their kids or something, no [more]," she said. "I had miserable pregnancies, that's why."

Clarkson had revealed while pregnant with Remy in November that she was getting "IVs and fluids" because of "all-day sickness."

She experienced similar symptoms with River, telling DeGeneres in 2013 that she was vomiting "a good dozen times a day."

Clarkson won the first season "American Idol" and has since released seven studio albums. She last released Piece by Piece in February 2015, which debuted at No. 1 on the Billboard 200.
