Clooney and lawyer Amal Alamuddin, 36, 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 on 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.

It is the second marriage for Clooney, 53, and the first for Alamuddin.
