Blake Lively Wedding Dress, Actress Wore Chanel

Blake Lively opted to wear a Chanel wedding gown down the aisle for her and Ryan Reynolds' secret wedding on Sunday, according to reports.

The "Gossip Girl" star married her boyfriend of less than one year at the Boone Hall Plantation in Mt. Pleasant, S.C., where an estimated 70 guests, including actress Bette Midler, witnessed the pair trade "I Dos," according to the New York Daily News.

While photographs of the couple's big day are yet to be released, it is believed that Lively, 25, wore a demure and unique Chanel wedding dress while Reynolds, 35, opted for a classic Hugo Boss tuxedo.

New York City jewelry designer Lorraine Schwartz allegedly made the duo's wedding rings and their $3,000 cake was reportedly baked by Maggie Austin Cakes in Maryland.

Florence Welch, of the band Florence and the Machine, reportedly performed followed by Midler at the intimate wedding reception.

Fans of the couple were stunned to learn that they had gotten married on Monday as the pair never confirmed rumors of an engagement. It s believed that the newlyweds planned the wedding in just one month and Lively requested time off from the "Gossip Girl" set just three weeks ago, a source reportedly told the Daily News.

The marriage marks Lively's first and Reynolds' second, the Canadian actor was previously married to "The Avengers" actress Scarlett Johansson, whom he divorced after two years of marriage in July 2011.

Prior to Reynolds, Lively had been romantically linked to actors Leonardo DiCaprio and her "Gossip Girl" co-star Penn Badgley.

The actress met Reynolds in 2011 while filming the blockbuster film "Green Lantern" and they began dating soon after.

Reports that the couple purchased a home together in Bedford, Westchester County, in early 2012 suggested that their relationship was getting serious and prompted rumors of an engagement.
