Hollywood A-lister George Clooney is apparently planning to seal the deal and get married to Lebanese-born, London-based lawyer Amal Alamuddin, his girlfriend of several months

Alamuddin was seen Thursday at a Los Angeles restaurant donning a “huge ring” while dining with the Oscar-winning actor, a witness at the scene told People magazine Saturday.

A source told the magazine that the engagement happened recently, but there were no definitive wedding plans yet.

The star of the smash hit sci-fi flick “Gravity” had attempted to keep his relationship with Alamuddin on the down-low and even denied having any current romantic ties.

But rumors began spreading after the 52-year-old Clooney was spotted on a dinner date with a mystery woman in Berners Tavern in London in October of last year.

The woman was wearing a figure-hugging red dress and, by all reports, was thoroughly enjoying the one-on-one time with her Oscar-winning date.

It didn’t take long before Clooney’s partner was identified as Alamuddin, 36, who specializes in “international law, human rights, extradition and criminal law,” according to the website of Doughty Street Chambers where she is listed as a barrister.

The site notes that she has in the past represented clients at the International Criminal Court, the International Court of Justice and the European Court of Human Rights.

Clooney is well known for his humanitarian work and in particular for campaigning for an end to the conflict in Darfur.

The London-based Alamuddin is currently representing WikiLeaks founder Julian Assange in his battle against extradition to Sweden.
