And a baby makes three!
The two Skyped in from separate locations as Kevin was currently in rehearsals for his upcoming Jonas Brothers tour.
Kevin admitted that he "was overjoyed" upon learning that his wife was pregnant.
"It's been the most exciting thing in my life so far," he revealed. "I'm ready to do this with Dani."
Meanwhile, the mama-to-be has had a rocky first trimester with baby Jonas, saying, "It's been a rough couple of weeks, but it's getting better."
Neither Kevin nor Dani know the baby's gender just yet, but they're are planning to find out as soon as they can.
"I want to find out, because I want to go shopping," Dani said as she laughed.
The brunette beauty is already planning her child's name, however, and says that the future moniker will be "definitely not classic, but nothing too crazy."
"Hopefully [the name] has a little Italian in it," she added.
Kevin also revealed to Rancic how his brothers reacted to the wonderful news.
"They're really excited," he said. "They shot their arms up in the air [when they heard]."
But Kevin is already a little bit nervous about letting one of his brothers babysit for the future bundle of joy.
"I don't know if I can trust Joe with the baby," he joked.
The loving couple also added that they've already succumb to inevitable pregnancy cravings and late-night trips to the grocery store.
"I know exactly what I want to eat for lunch or dinner," Dani explained of her newfound (and sudden) cravings. "I want chicken or peanut butter and jelly sandwiches or I want chocolate."
And Kevin is already proving to be a doting caretaker. He revealed that he's already been on one trip to the store for his wife. Now that's love!
"It's going to be a great start to the year," Kevin added.
The two originally met in 2007 and tied the knot in a snowy ceremony at Oheka Castle in New York's Long Island in 2009.
Congratulations you two!
