Carrie Underwood knows how it feels to be betrayed, says Judy Bachrach in Allure. In college, the platinum-selling singer dated a guy who cheated shamelessly on her. “I don’t want to name names, even though he probably deserves it, but he fooled around. Oh, yeah. And lied! He was a gooood liar. And he seemed perfect in every way!” Underwood immortalized such scalawags in her hit single “Before He Cheats,” wherein she sings about ruining a straying lover’s 4x4. Underwood’s also been hurt by family members who suddenly showed up, palms open, after she became famous on American Idol, and started making money selling records. “You never really know why somebody wants to be around you, or if they do genuinely like you. I wish everyone had a label on their forehead so you could automatically tell their intentions. Sometimes you just wish that no one wanted anything from you.” Rather than take chances, Underwood has come to trust no one. “I’m not a person to sit down and have in-depth, feeling-related conversations with anybody. I like to talk about football and things that aren’t heavy. Or not talk at all.” And she’s gotten proactive about protecting herself. “I really have gotten rid of a lot of people in my life,” she says, “that don’t need to be there.”
