In your mind, Kelly Rowland might be the teenager of Destiny's Child fame, or the solo artist with dance floor anthems like "Commander." But these days, Kelly's much more than a pop star. She's an entrepreneur, philanthropist, writer and mother of two beautiful children. She recently published a children's book called Always with You, Always with Me, her ode to working moms.This week on The Limits, as we gear up for Mother's Day, Jay and Kelly explore motherhood: how Kelly juggles being a good mom with her career, how she strives to be transparent with her children about fame and celebrity, and how she cared for her own late mother in her final days.For sponsor-free episodes, weekly bonus content, and more, subscribe to The Limits Plus at plus.npr.org/thelimits.
