A lot has happened since Clarkson and Blackstock said "I do" three years ago. The couple welcomed daughter River Rose in June 2014, and son Remington Alexander in April.
ET caught up with the singer earlier this month, where she couldn't help but gush about how her life has changed since becoming a mom to River and Remy, as well as stepmom to Blackstock's two children, 15-year-old Savannah and 8-year-old Seth.
"I feel way more confident, way more empowered and way more like I've got this," she confessed. "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," she said, before crediting her husband for juggling his share of the responsibilities. "We're definitely a team."
