Morreale married country singer Kacey Coppola Saturday on the island of Antigua in the Caribbean.
"Even though I've now seen the most beautiful bride in the world, if I only knew her in the dark, I definitely would've still married her," an exuberant Rossi tells PEOPLE.
The couple met in 2008 on the set of the Country Music Television show Can You Duet. Rossi hosted the show and Coppola and her sister, Kate, competed. The sisters finished fourth on the competition, but Kacey walked away with an even better prize: her now-husband.
The pair, who exchanged vows at The Sandals Grande Antigua Resort in Dickenson Bay, will split their time between Nashville and Los Angeles.
Morreale's show, Dating in the Dark, puts three guys and three women into a house together, but they don't meet until they're introduced in a pitch-dark room. The show, which bills itself as the "ultimate blind date," kicks off its second season Monday at 10 p.m. ET, following the premiere of Bachelor Pad on ABC.
