George Clooney and Amal Alamuddin will reportedly tie the knot this weekend in Venice, Italy.

The couple is said to have two wedding ceremonies, one on Saturday, Sept. 27, followed by a civil ceremony on Monday, Sept. 29, the Associated Press reported.

Alamuddin flew into Milan, Italy, from London, England with her mother, Baria Alamuddin, Thursday Sept. 25, according to People. The 36-year-old bride-to-be was all smiles when she arrived at the airport carrying a light amount of luggage, including a large black octagon garment box. See a pic of her here.

Meanwhile, Venice city officials Thursday ordered to close a walkway fronting the Grand Canal on Monday to prevent crowds from gathering and creating a safety risk during the couple's civil wedding ceremony, according to AP.

The city order will close pedestrian access to walkways accessing the 16th-Century Cavalli Palace for at least two hours Monday, citing "the George Clooney wedding."

A Venice city official, who wished not to be named, told AP that police requested the closure of the walkway to prevent crowds from gathering and creating a safety risk. The official noted that this will not be the first time the area will be closed as temporary closures of it have taken place several times before for both public and private events.

The official added that only city offices are affected by the closure area, and not private commercial establishments that cater to tourists.

Clooney and Alamuddin's wedding celebration, which is believed to start tomorrow, will be attended by big names in the entertainment business, including Angelina Jolie, Brad Pitt, Mrs. and Mr. Cindy Crawford, Andrea Bocelli and Bono and Matt Damon, according to Philadelphia Daily News.

The 150 guests are believed to split time between Hotel Belmond Cipriani, on lil' Giudecca island, and Aman Canal Grande, on the Grand Canal.

The 24 rooms of Aman Canal Grande, a seven-star hotel built in 1550, are fully booked this weekend as well as Belmond Cipriani, a five-star hotel which has long been a Clooney favorite, according to New York Daily News.

Walter Veltroni, the former mayor of Rome, will conduct the wedding ceremony of the high profile couple, who got engaged in April, People reported.
