For now, the pair -- who tied the knot in a gorgeous Rhode Island ceremony in August -- are enjoying newlywed life. "Thanksgiving was fun. His parents came down and we had a joint family Thanksgiving, and it's really just funny to be at dinner tables and be like, 'You're married and you're married and we're married,'" Iaconetti shared. "It's a whole different feel."
"It feels old," Haibon said. "My parents are married, your parents are married, I'm married!"
"It feels mature," Iaconetti conceded. "Yet at the same time, I go, 'Mom, I put a load of laundry in the laundry room so you can get that.' [I'm a] kid and adult at the same time still."
Friday's Jingle Ball also marked former Bachelor Chris Soules' first red carpet appearance in two years, following his involvement in a fatal car crash in 2017. Soules -- who was charged with leaving the scene of a fatal accident and received two years probation -- opened up to ET about reentering the spotlight.
"It has been tough but it makes you appreciate the people around you, family, friends -- and how hard things can get, you just have to press on," he said.
Both Iaconetti and Haibon shared with ET how thrilled they were to spend time with Soules, and how delighted they are that he is able to get back to his life.
"Chris has been a friend and it was just a horrible situation that happened a couple years ago, and I remember first hearing about it, and it's that moment where your heart sinks and you have no idea what's going to happen, because Chris is such a good friend, and it was tragic what happened," Haibon shared. "You go through so many emotions as a friend, because you just don't know the situation and you're hearing rumors about what exactly happened and what didn't happen."
"I'm just really happy for him right now, that he's hopefully being able to get back to his life, because I don't think he was able to for the last few years. And so, we'll still be there to support him. We watched football together a couple Sundays ago," he added.
"He's just such a kind guy, so good-hearted," Iaconetti chimed in. "And I'm happy to see him out here living."
"There are people in his life who are way more involved than us that did a lot more. So, we're here for him if he needs anything, and I think that's all I can really say about it," Haibon expressed.
