"Gossip Girl" star Blake Lively and Hollywood star Ryan Reynolds tied the knot Sunday night in the Palmetto State of the US, according to US media.

Florence Welch, a good friend of Blake Lively, performed three songs live.

The newlyweds planned the wedding in just one month. Lively asked for days off from the "Gossip Girl" set just three weeks ago.

Their $3,000 wedding cake, baked by Maggie Austin Cakes in Maryland, was driven eight hours and across three state lines to the reception.

Reynolds, 35, and Lively, 25, met while filming the 2011 film "Green Lantern". They have been dating about a year and bought a home together in Bedford, Westchester County, earlier this year.

Reynolds was married for two years to actress Scarlett Johansson. They split in 2010. Lively's mother and sister were also spotted in town. About 70 guests attended the ceremony.
