The Jonas Brothers - Kevin, Joe and Nick - were expected to arrive at Huntington's Oheka Castle Friday in preparation for Kevin's wedding to Danille Deleasa this weekend, RadarOnline.com reports.
The family has rented out the whole second floor of the former estate of financier Otto Kahn, according to the site. The wedding party will be staying overnight in what was once the second largest private home in the United States.
The ballroom, where the rehearsal dinner and a skating party is reportedly being held Friday night, is decorated with Chinese lamps inscribed with the couple's names. Radar reports that the wedding tent will be similarly decked out, in case anyone forgets that it's Kevin and Danille who are getting married.
About 45 people are expected for the rehearsal dinner and party. It's not known how many will attend the wedding, but the tent reportedly can accommodate up to 300.
