Snooki's not good at keeping secrets. We all knew she was pregnant a good month or two before the official announcement and we all knew she was engaged to her baby daddy, Jionni LaValle, long before she tweeted the following twitpic yesterday:

No, she's not just showing off the latest in guido bling; she's finally revealing that she's engaged. Snooks tweeted the photo along with the caption, "My FIANCE!" Nice reveal, Snickers, but we all heard the news about six weeks ago. But hey, we don't wanna take away from your big moment. Congrats to the happy couple and their coming gwaby (that's a guido baby). We're sure everything will go smoothly…until The Situation shows up at the hospital to confront Jionni in the delivery room. Enjoy that!
