Hollywood superstar George Clooney is reportedly set to marry his fiancee Amal Alamuddin on September 12 this year.

Alamuddin is apparently poised to send out save the date cards warning friends and family that they will need to fly to Italy and then to Lebanon in September, reported Showbiz spy.

"September 12 is the date they are aiming for. Everyone thinks they will marry in Lake Como where George owns a beautiful home but Amal feels that is too public.

"They are looking to host a small wedding in an Italian village where they can control the photographers.

But they haven't decided yet. They will then have big parties for her relatives in Lebanon and London," a source said.
