Justin Timberlake and Jessica Biel will marry in a $5 million Italian ceremony.

The couple are planning to wed in the European country in October and Jessica has been busy planning every detail of their big day. "Jessica has claimed she is too busy to plan a wedding but she actually has been very involved in all the details, like every bride," a source said.

Wedding planner Diana Sorenso recently planned some nuptials at 19th century boutique hotel Palazzo Margherita and claims the star-studded nuptials will be held there. "I've heard the wedding will be intimate, in the palm-tree lined outdoor garden area, just aside from the stunning black bottom pool and giant pergola. There will be flowers galore and it will be extremely elegant - the most stunning the palazzo has seen yet," she said.

Those expected to attend include Amy Adams, Ellen DeGeneres and Justin's former *NSync bandmates and guests won't have to spend any money as the generous couple are paying for everything. "Justin and Jessica plan to pay for the entire trip for all their guests and help. That includes private jets, five-star hotels and rental homes, plus food fit for a palace," an insider said.
