Is This Lady Gaga's Engagement Ring?

The wedding rumour mill has gone into overdrive after Lady Gaga posted a picture on Facebook of a whopping diamond ring on her engagement finger.

The singer is obviously head over heels for beau Taylor Kinney, who starred in The Vampire Diaries and Gaga's video for You and I.

Reports recently suggested Taylor was seen shopping for a ring in Chicago, although sources said he made mention of a "promise ring".

So is this an engagement sparkler, or a just a "promise" that the pair are committed to each other? Judging by Gaga's enormous smile, we're currently guessing the former.
