Kevin Jonas On Engagement: 'It's Going Great'

'We're having a good time,' Jonas says of time with his fiancée.

As millions of girls around the world shed a tear over the news of Kevin Jonas' engagement to longtime girlfriend Danielle Deleasa, Kevin's brothers expressed their excitement about adding a sister to the Jonas family.

"It's going great," Kevin told MTV News about the engagement, as his brothers excitedly gave him a hug. "No date yet — me and Dani are just working everything out and figuring everything out. We're having a good time."

"We're happy for him," Joe added. In a tweet posted by the brothers just hours after the pair's engagement news broke, Joe and Nick wrote, "Congrats big brother ... Dani welcome to the family. We can't wait to have you join us on the road! Love Joe and Nick."

Kevin, being the romantic that he is, showed up to Deleasa's New Jersey doorstep after flying overnight from a show in Toronto. He got down on one knee and asked his girlfriend of two years to marry him with a three-carat solitaire cushion-cut diamond surrounded by 210 round, brilliant-cut pavé diamonds. Kevin designed the ring himself, with help from Jacob the Jeweler.

"She said yes, yes, yes, like 500 times super fast in a row," he recalled. "It was tough performing [the night before], knowing that I was going to ask the biggest question in my life to the most amazing girl in the world," Kevin said.

"It is such a blessing that she will be joining our family. ... Family is very dear to us, and we hope we have raised Kevin to be a wonderful man and husband. Please join us in our family's celebration and in congratulating Kevin and Danielle. Thank you for all of your support," Kevin's parents, Kevin Sr. and Denise, said in a statement.
