Los Angeles - Matt Damon is expected. So are Brad Pitt, Angelina Jolie, Julia Roberts, Sandra Bullock, Ellen Barkin, Bono - and 100 cases of tequila.

The guest list for Oscar winner George Clooney's three-day wedding festivities has been leaked in the Italian media, and A-listers are said to have been invited, report USA Today and The Hollywood Reporter.

Clooney, 53, has said he met human rights lawyer Amal Alamuddin, 36, in Italy and will marry her in Venice.

The Daily Mail, quoting Us Weekly, says the pair will wed on Sept 27, with guests including Clooney's best friend, bar mogul Rande Gerber, and his wife, model Cindy Crawford. People magazine says Gerber has been photographed loading 100 cases of award-winning Blanco, Reposado and Anejo tequila onto a jet headed from California to Italy.

Italian media outlet Corriere della Sera says Clooney and his fiancee will be married by his friend, former Rome mayor Walter Veltroni, at Ca'Farsetti, a 14th century palace that faces the Grand Canal.

The guests are said to be staying at the Hotel Aman, Venice's new seven-star luxury haven where rates begin at US$1,600 a night.

The bride will wear Oscar de la Renta, the groom will wear Giorgio Armani and Lana Del Rey will sing, say reports.
