George Clooney, Amal Alamuddin engaged?

Hollywood superstar George Clooney has reportedly popped the question to his new girlfriend Amal Alamuddin after she was spotted showing off a diamond sparkler on her ring finger few days ago.

Clooney, 52, and Alamuddin were first spotted together publicly in October last year, reported the Huffington Post.

"George and Amal are trying to keep things very low-key but they also aren't really trying to hide this, it doesn't seem. I think it's like they want the people they love to know that this is real, that they plan on being together forever," a source said.

The pair have apparently been getting serious in recent months and were most recently seen at a special screening of Clooney's movie 'Monuments Men' at the White House in February.

The actor's romance with Alamuddin came shortly after he split from Stacy Keibler last July, who reportedly ended their relationship because Clooney did not want to settle down and have children.

The Hollywood hunk was previously married to Talia Balsam and has since had notable relationships with Sarah Larson, Elisabetta Canalis and Keibler.
