“Us moms can get stuck in our houses with the kids,” the singer, 32, tells PEOPLE exclusively. “Sometimes it’s really nice to just get outside [and] get your own identity back.”
Clarkson — who gave birth to daughter River Rose last June and is stepmother to her husband Brandon Blackstock‘s children Savannah and Seth — says she enjoys sneaking in “girlie days,” but she loves date night with Blackstock even more.
“As a couple, we think that date nights are important,” the American Idol alum and guest mentor says. “We are both from broken homes and as a result you may not take time for yourselves as a couple. So we love our date nights.”
