People reports that Taylor Swift seems to have found a new love interest in pop group One Direction's Harry Styles. An onlooker told People that while Swift was on the set of The X Factor on Thursday, Styles was close by watching her rehearse the debut of her song, "State of Grace," which she performed on the show later that night. The onlooker said, "I had to literally do a double-take. He was smiling at her while she rehearsed. When she was done he jumped up on stage, picked her up, put her over his shoulder and carried her off stage. The whole crew was really surprised." It is also reported that the host of The X Factor, Mario Lopez, said on his radio show Friday that he saw Styles and Swift "hand-in-hand."
