People magazine reported that the couple, who have been dating about a year, tied the knot yesterday (September 9th) in South Carolina.
People added that Florence Welch -- of Florence and the Machine -- is Blake's good friend, and performed three songs live.
Lively, 25, and Reynolds, 35, starred together in 2011's Green Lantern. They recently bought a house together in New York and have laid relatively low throughout their courtship.
- This is the first marriage for Blake; Ryan was previously married to Scarlett Johansson.
