This is a significant time in the life of Joe Jonas.

Having broken away briefly from the comfort zone of performing with his brothers, the singer has also embarked on a serious relationship with a Twilight Saga star. How are things going with Ashley Greene?

“[It] feels good," Joe says in the April issue of Details. "I think what works about it is she really puts my feelings first. She understands my busy schedule. She’ll fly out to my shows. She’s been to places in South America that I can’t even pronounce.”

As for his solo album and an interesting story about his sister-in-law? Read on for more excerpts from this interview.

On his upcoming CD: “I wanted to do something you could hear in a club or something you could dance to, something that’s fun - something that’s me. I think it was definitely because I was getting older. But it was also a kind of a scary thought. ‘Cause you go, ‘I don’t want to offend my brothers.’ You know?”

On recent heartbreak: “I won’t say her name. But I was in a relationship, and we tried to work things out, and she, you know, I was really upset because she, she broke up with me.”

On Danielle Deleasa: “Actually, I hit on her first. And after that she and Kevin hit it off, of course. Now we have a fourth person traveling with us everywhere, so that’s a different thing completely.”
