The party of the year is happening here: the fresco-adorned Aman hotel on Venice's Grand Canal is feverishly preparing for
wedding to Amal Alamuddin, his Lebanon-born British fiancee.
Hollywood stars and the world's paparazzi have already begun arriving for the nuptials of the world's most sought-after catch, who will, sources said, celebrate with 136 guests at the exclusive seven-star hotel in the 450-year-old Palazzo Papadopoli.

The pair are expected to be officially married in a civil ceremony on Monday, but the city of masks is preparing for a weekend of serious partying before then.
"Clooney's on everyone's lips here in Venice, the girls in particular are all in a tizzy, they'll be lining the banks of the canal to see him," said watertaxi driver Bruno Bartolini, who said it would be "a fantastic party. The city's ground to a halt because they're using the grand canal, but what does that matter: there's nothing better than getting married in Venice," Bartolini said.

Guests including Brad Pitt, Angelina Jolie, Sandra Bullock and Matt Damon are set to stay at the Hotel Cipriano on the island of Giudecca, where they are expected to dine in style Friday evening with the groom and his glamorous bride-to-be.
The reception will take place on Saturday at the luxurious water-front Aman, where guests will be escorted by police boats keen to keep over-excited Clooney admirers and hundreds of photographers at a distance.
They'll be met with lashings of fizz and canapes in the garden, an oasis sheltered from the bustle of the canal, before sitting down in the main library to a sumptuous five-course dinner rustled up by a renowned Italian chef, according to a source close to the hotel.
The Aman's restaurant will be then transformed into a nightclub, where they'll dance the night away, a source said.
The hotels are said to be bound by strict confidentiatlity agreement and are booked for September 25 to 29. Both the actor and Amal have arrived in Italy ahead of the ceremony. Despite his fortune, Amal’s parents are believed to have insisted on paying for the big day.
The singer Lana Del Rey is reported to be preparing to serenade 53-year-old Clooney and Alamuddin, 36.
Speed boats will be banned from stopping in front of the hotel to keep goggling to a minimum.
Rome's former mayor Walter Veltroni, a long-term friend of Clooney's, will be performing the civil ceremony, which is likely to be held in the town hall, the stunning Ca' Farsetti 14th century palace opposite the Aman hotel.
The streets around the town hall will be off limits to the public from 12 noon (1000 GMT) for two hours on Monday, when the ceremony is expected to take place.
Crowds of tourists are eagerly snapping photographs of the town hall and Aman from the water ferries, or the locals staking out the best viewing positions in houses along the canal.
All desperate for a glimpse of the erstwhile bachelor in his Armani suit and Alamuddin in an Alexander McQueen creation designed by Sarah Burton, the woman behind the gown worn by Britain's Kate Middleton at her wedding to Prince William in 2011.
Alamuddin, who moved to Britain with her family as a three-year-old, is a top human rights lawyer who met the Hollywood star through his humanitarian work.
Clooney is madly in love with his fiancée and said at a recent event, "I met my lovely bride-to-be here in Italy, who I will be marrying in a couple of weeks in Venice, of all places. Amal, I love you to death and I cannot wait to become your husband."
