George Clooney's wedding will feature in America's Vogue magazine.
The 'Monuments Men' actor and human rights lawyer Amal Alamuddin are set to tie the knot in Italy next month, and among the guests at the celebrations will be the publication's editor-in-chief Anna Wintour.
A source said: "She wouldn't go there and not cover it."
Amal is expected to wear a gown created by Oscar de la Renta and, because the designer is a close friend of Anna's, the dress will feature heavily in the wedding coverage.
The insider told the New York Post newspaper's Page Six column: "She and Oscar are such good friends and [she'd] want to give him some attention."
Meanwhile, the groom will reportedly wear Giorgio Armani. A team of designers recently flew to his Italian estate for fittings with the 53-year-old actor and the male members of the wedding party.
A source told WWD: "They're locked and loaded."
George and Amal, 36, are planning a small and intimate wedding but will also celebrate with a number of parties before and after the nuptials, which are reportedly taking place in Venice on September 20.
A source said: "They're going to have top security, but include a really small group. Very intimate, and mostly family."
The couple got engaged in April after seven months of dating.
