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