With the details all ironed out about which Jonas Brother will be Kevin's best man when he gets married, the boys now have to figure out what they're going to do for his bachelor party. And since both Joe and Nick are his best men, the responsibilities fall on both the brothers.

"It will be good, clean fun," Nick told People magazine of Kevin's last night as a single man. "We're going to have a good time with friends and family."

"It won't be in Vegas," Joe added. "Vegas is not really the ideal place. We are thinking somewhere even cooler and better."

The only problem the brothers are having in planning the celebration is that Kevin wants to be involved in the process. Well, they're not going to let him. "It's a big deal, but Kevin kind of has already planned it himself," Nick said. "He will give us suggestions on what he would like and we keep on trying to tell him no. We're like, 'You have no involvement in planning this. Just get ready to have a good time.' "

Joe, who is busy filming "Camp Rock 2: The Final Jam" with his brothers, is definitely against Kevin chiming in. "We're not going to let that happen," he said. "Nick and I are in charge and we have to remind Kevin that we'll take care of it."

He added that he can't wait to have Kevin's fiancée, Danielle Deleasa, join the family: "This is going to be a new step in all of our lives. We are willing to take it and we're excited for him. It's great to have a sister in the family."

While Kevin might be excited about getting married, he's not quite ready to talk about starting a family. Kids, he explained, aren't in the plans just yet. "It would be incredible to be a dad and raise a family," he said. "I hope to someday. But it won't be anytime soon."
