It has been reported that Florence Welch sung three songs live at the reception, and that a cake for the party was delivered from Virginia.
The reception is believed to have taken place in a white tent on the property.
The pair are said to have been dating since October 2011 following Reynolds's divorce from Scarlett Johansson, although they have been low-key about their relationship. Representatives for the actors had no comment.
Reynolds and Lively were rumoured to have got married earlier this summer when a police report referred to the Gossip Girl actress as Reynolds's wife.
However, this was believed to have been a clerical error.
