Joe and Nick Jonas are organizing their eldest brother’s Kevin bachelor party. The two younger brothers are planning a ‘clean and fun’ celebration but they struggle to keep Kevin away from the details. "It's a big deal, but Kevin kind of has already planned it himself," Nick said. "…We're like, 'You have no involvement in planning this. Just get ready to have a good time.' " “It will be good, clean fun," he told People 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 said. "Vegas is not really the ideal place. We are thinking somewhere even cooler and better."
