According to E! Online, the ceremony is to be held at the French chateau-inspired Oheka Castle in Long Island, NY, which is where former 'N Sync star Joey Fatone married Kelly Baldwin in 2004.
The oldest member of the Jonas Brothers confirmed his engagement to Deleasa in July, after popping the question at her New Jersey home following a concert in Vancouver.
In September, Jonas made both of his brothers his best man for the occasion.
