In an interview with Refinery 29
, the 34-year-old country crooner reveals that her stepsons, Mason, 13, and Jake, 10, will spend Sunday with their mother, Brandi Glanville
, but will celebrate Stepmom'sDay with her the following weekend. "I love the fact that there is a Stepmom's Day and an option [for stepparents to celebrate]. It's so different for each family," she says. "For me, we have the kids half the time, so I feel like I am mothering, which is crazy as someone who has never had [biological] children before. I think it's great."
