Maybe even before,” Dixon tells PEOPLE. “I can’t imagine how much of a mess I’m going to be!” The singer, who placed seventh on the eleventh season of American Idol, was just as emotional after popping the question this September in Disney World when he hid the ring in Cinderella’s glass slipper for Coggeshall, 27, to find. “She said yes!!!!!! #disneyworld #bestdayever #icried #shedidnt,” Dixon, 24, captioned his Instagram photo collage. The couple met through a mutual friend three and a half years ago at a show in L.A.’s Viper Room. After the wedding they’ll live together in Dixon’s home in Nashville. Dixon, who released his second album of Christian music, Anchor, last year, admits to feeling a few jitters about their upcoming nuptials – which Coggeshall says will have a “royal” feel – but he says, “Honestly, as long as she says ‘I do,’ I’m good!”
