This just might be the first time in our lives we use the phrase, "never thought I'd see the day." According to People Magazine, George Clooney is engaged. 

The publication says it's confirmed through an unnamed source that Clooney put a ring on the finger of Amal Alamuddin, a human rights lawyer who was first reported to be his girlfriend just five months ago. (Via HLN)

People's source says, "George and Amal are trying to keep things very low-key but they also aren't really trying to hide this. ... They plan on being together forever."

Thirty-six-year-old Alamuddin was apparently spotted at dinner with Clooney Thursday, and had a ring on that all-important finger. If this is true it's such a 180-degree turn for Clooney, we don't even know where to start.

So, yeah, it's pretty mind boggling. How this woman changed the 52-year-old's long-made-up mind is unclear. Some reports note that Alamuddin is not in the entertainment industry, arguing that could be key.

Many of his other paramours are in front of the camera, including Clooney's last serious girlfriend, Stacey Keibler — who just got married and is now pregnant. (Via Us Weekly)

So far there hasn’t been a comment from Clooney himself. So, maybe Keibler's newfound stability sparked something in the actor's head, maybe he's just finally found the one, or maybe the world is ending. We'll keep you posted... if we're still here.
