Forget about all those other secret celeb weddings, this one takes the (probably five-tiered, very elegant and tasty) cake!
A source tells E! News that the guests included close friends only, but also some Hollywood types, including Blake's manager.
The newlywed's reception took place underneath a large white tent with music from Lively's friend Florence Welch (yes, she of Florence + the Machine) along with a DJ. According to People, the actress's mother and sister were spotted grabbing lunch in town earlier this weekend with Bette Midler—however, a rep for Midler told E! News the star did not attend the wedding.
News of the top secret ceremony was first tipped by local radio station 95.1 FM, which tweeted, "Hold up, there's another story that it's Ryan Reynolds and he married Blake Lively at the Cotton Docks today!"
The station's Kelly Gukanovich tells E! News, "A few days ago, I heard Ryan was back in town. Then today, lots of signs went up at Boone Hall Plantation stating that it was holding a private event, so no one could get into the area. I also started hearing rumors that a celebrity wedding was taking place.
"I am being told there were around 60 people at the event and that a local restaurant may have catered it. Ryan has always loved it here and when he got together with Blake, he started to bring her here, too."
The stars' reps were not immediately available for comment.
However, a source close to LIvely says her inner circle was shocked that she and Reynolds tied the knot so fast, having only "gotten over" her split with Leonardo DiCaprio just a year ago.
Wedding rumors about the duo went wild back in July, but that turned out to be a bit premature.
The Green Lantern costars' relationship first went public less than a year ago when they were spotted together at multiple locations. Once word was out that they were an item, the two became inseparable, and they even started nesting together.
This is the second trip down the aisle for Reynolds, who married Scarlett Johansson in 2008 and the couple divorced two years later, citing irreconcilable differences. Lively's previously dated DiCaprio and her Gossip Girl costar Penn Badgley.
Congratulations to the newlyweds!
