"We are not having any more kids," Clarkson, who is the mother of 2-year-old daughter River Rose and 6-month-old son Remington Alexander with husband Brandon Blackstock, exclaimed. "I mean, there's no time for more kids, yeah. Just like fitting everything in is hard enough, and I hate pregnancy. Like, with a capital H."
And she's not kidding. "I was mid-pregnancy with Remy and I made my husband go [get] snipped," Clarkson revealed. "He didn't -- I didn't have to force him. He was running to the doctor. We both were like, 'Nope!'"
Clarkson added that because there's "only so many hours in the day," balancing motherhood with her successful career can be quite challenging. Regardless, she told ET that being a mom is "awesome" and "cool."

"I never thought -- I learned that I'm like my mother. I discipline like my mother, I shop like my mother, I'm everything like my mother," she joked. "But I don't mind. I'm not like one of those people that's like, 'Oh, no.' I'm like, 'She was pretty cool.'"
"I'm pretty independent," Clarkson continued, adding that the companion doll for "River Rose and the Magical Lullaby" is currently available at Toys R Us. "I turned out alright, so hopefully our daughters do [too]."
The Texas native also talked new music, as she's currently in the studio creating her dream soul/R&B-inspired album with Atlantic Records. Clarkson was previously signed to Sony Music's RCA Records ever since she won the first season of American Idol in 2002.

"It [was my] first time to pick a label since Idol, so that was pretty exciting," Clarkson said of the long-term deal, which she announced in June. "We both have the same vision, Atlantic Records and I."
"We both want something soul and urban, still pop but, like, just a different direction," she added. "We've given 14 years of solid pop rock, so I feel like it's time to venture at this point. But this is basically the album I've been dying to make since I was a kid. And it sounds good. I'm very excited about it."
Clarkson continued to gush over the new record label, telling ET she's in "love" with the new company because "they know that I have a desire to make a country album as well one day."
"They're totally into it -- they just love art for art -- so, that's what was very exciting about signing with them," she explained. "They're willing to let artists be artists."
