A source confirms to PEOPLE that the couple tied the knot Sunday night at Boone Hall Plantation in Mt. Pleasant, S.C., just outside of Charleston.
The reception took place in a white tent at the plantation on Sunday evening. Florence Welch (of Florence and the Machine), a good friend of the Gossip Girl star, performed three songs live, and there was also a deejay who spun tunes. PEOPLE also confirmed that a cake was being driven down from Virginia for the event.
Lively’s mother and sister were also spotted in town, and a source told PEOPLE that the two had dinner in Charleston with Bette Midler earlier in the weekend.
Reps for the two actors had no comment.
