George Clooney and his fianceé Amal Alamuddin have posted a legal notice declaring their intention to marry in Italy.

Clooney and the Beirut-born London lawyer announced their engagement in April, though the pair have not yet announced a date for their nuptials.

A spokesman at the register office at London's Chelsea Old Town Hall confirmed Thursday that the couple posted a legal document for a British national who is marrying abroad.

A photo of the notice published by the Daily Mirror newspaper showed the pair's names, ages and occupations. It also showed they plan a wedding in Italy.

The document has been taken down after being on display for the requisite 21 days.

The nuptials, rumoured to take place next month, would be a second marriage for Clooney, 53, and the first for Alamuddin, 36.
