Nick Jonas finally spoke publicly about his split from Olivia Culpo. The "Give Love a Try" singer recently sat down for an interview with ET Online originally to talk about his music career and his longtime battle with diabetes, but the host couldn't resist asking him about his heartbreak.

"I'm doing OK. It's very tough and we had a beautiful two years together and [I have] nothing but love and respect for her," Jonas told the host. He said that for now he spent his time "focusing on my work and staying as busy as I can, as creative as I can be. These are the times you've just got to dive in and get lost in your work and that's what I'm trying to do."

Although the split was hard, Jonas said that it taught him something. "I have regrets about not being open with relationships in the past. That's the thing that makes it actually more challenging," Jonas admitted. "On many levels you try to hide the relationship or do things to make it more private but that just adds more stress on the relationship."

"Whereas this relationship I was in was open and public and there's a lot of comfort in that and support," he continued. "So yeah, I think it's the opposite actually. But it's this part of it that makes it all harder afterwards."

When being asked if he gave his big brother Joe Jonas, who's been rumored to be dating Gigi Hadid, advice on dating famous stars, the "Jealous" singer said, "Their relationship is their own thing." He added, "I'm happy to see my brother happy, it's a great thing. You love seeing your family happy. She's a great girl, and I love spending time with them together, but as far as the details of their relationship, that's on them."

Jonas and Culpo had dated for two years before they broke up less than two week ago. Previously, the former Miss USA also addressed her heartbreak in a social media post.
