"No, not that I know of at least," the songstress tells CBS This Morning's Gayle King in an interview scheduled to air on Wednesday regarding such speculation.
In fact, Underwood insists she's a fan of her fellow country artist and even has a favorite song.
"I realy like 'I Knew You Were Trouble,'" Underwood says. "It sounded a lot different for her. I liked the branching out, trying some different sounds."
As for how she thinks rumors of a riff between her and Swift even got started, the Grammy winner noted, "In every magazine, in pretty much every newspaper or on gossip TV shows, they can just get away with it by saying 'a source said' or 'an insider said.' I've read the most ridiculous things about myself when people do that."
