It's finally happened. And it looks like Jennifer Aniston can close the chapter of singledom. The wedding was so top secret that even guests didn't know, until they arrived. From People:

"Guests were told it was a birthday party for Justin. Jen and Justin wanted to surprise guests, and guests were certainly surprised," a source tells PEOPLE. "Jen has been very good at keeping her wedding planning secret. Only her closest confidants knew that the party was actually a surprise wedding."
