We can always count on Kelly Clarkson to keep it real!
The 34-year-old singer got candid about her struggles with breastfeeding, revealing that trouble with her thyroid could have been to blame. In an interview with Jenny McCarthy on SiriusXM, the host offhandedly asked Clarkson, "Are you breast feeding? Is that too much information?"
"No, maybe it is, but I'll tell you!" Clarkson hilariously responded.
"I actually pumped like crazy, like, 40 ounces a day, and then I just went dry on both pregnancies," she revealed. "For, like, three or four weeks straight, I was crazy. I was like, 'I'm a rock star!'"

Clarkson went on to say that her doctor suggested that her ongoing medical issues with her thyroid could have stopped the milk from flowing. "I have a thyroid that doesn't work," she said. "Mine is, like, non-existent."
Clarkson welcomed her first child, daughter River Rose, with husband Brandon Blackstock in 2014, and her second, son Remington Alexander, in 2016. Clarkson is also a step-mother to Blackstock's son and daughter from his previous marriage. Clarkson says that their family is now officially complete.
"Shop is closed," she told ET on Tuesday. "Things have been taken out, so that cannot happen. We're done."
Focusing on their family, Clarkson had plenty to gush about when it comes to becoming a mom.
"It so cheesy, [but] I feel way more confident, way more empowered, way more like, 'I've got this!'" she said of being a parent. "I just feel like I can do anything. I feel like the head of a village."
