McCarthy usually hosts America's long-running New Year's Rockin' Eve from Times Square on the last night of the year, but she's taking the evening off next week, so she can ring in 2020 at home with her family.
"It's amazing. To be able to spend some time together this Christmas and not have to think, 'We have to leave tomorrow for Times Square for New Year's Eve'," Donnie told Closer Weekly. "We're going to spend the holidays together, not on television, for the first time in a long time. It's just going to be great."
"You know, it's going to be the first New Year's since we've been together that we don't have to stop kissing at midnight. We won't have Ryan Seacrest in our ear saying, 'Donnie, Jenny, what do you have to say?'."
The star, who wed Jenny in 2014 after a whirlwind romance, joked: "We'll kiss this year, we may or may not broadcast it live."
Jenny's spot will be filled by actress and singer Lucy Hale, who usually hosts the New Orleans portion of the end-of-year show.
