Kelly Clarkson "would die" if she got pregnant again.
The 'Since U Been Gone' hitmaker - who has River Rose, two, and five-month-old Remington Alexander, with her husband Brandon Blackstock - insists she won't be having any more children as pregnancy is always "horrible" for her.
She said: "Everyone's like, 'Oh, you're getting your tubes tied...' No, they're gone. My husband, like, while I was pregnant we agreed that he was going to get snipped ...
"We have magical babies together ... They're amazing, but I have the worst pregnancies. I would die if I had to do it again. It was horrible."
And whilst the 34-year-old singer's pregnancies were painful and difficult, she doesn't regret having her two kids.
Speaking to Access Hollywood, she added: "Nausea is for weak people. It was, like, hospitalisation. It's, like, bad. I had the worst pregnancies ever. I would end up in the hospital, dehydrated. People had to come to our house and I'd be on fluids.
"Apparently that's what it takes to make amazing babies, because they're both stellar. We've made them and it's done."
Meanwhile, Kelly recently revealed she feels "way more empowered" as a mother.
She said: "Having kids cuts out all the bulls**t in the sense that I don't have time to do stuff I don't want to do anymore. I don't have time to make you feel like it was your idea. I just don't have time for it anymore, so it definitely cuts through the bulls**t and you just go straight for what you want ...
"It sounds so cheesy, but I feel way more confident, way more empowered and way more like I've got this. You just have so much going on all the time, especially because I'm a working mom - so many moving parts and so much navigation - that I just feel like I can do anything. I feel like the head of the village."
