Just days after the tabloids declared their relationship to be on the rocks, there’s another marriage rumor making the rounds about Hollywood hunk Ryan Reynolds and his Green Lantern co-star, Blake Lively.

Except unlike the last wedding rumor – this one is true.

Reynolds and Lively tied the knot at Boone Hall Plantation in Mount Pleasant, S.C. on Sunday night – news that broke exclusively here on FITS.  The couple have made several trips to Charleston, S.C. in recent months – and were spotted there again this weekend getting ready for their big night.

According to our sources, Reynolds and Lively were wed in an intimate ceremony at Boone Hall’s “Cotton Dock” – which was decked out Hamptons-style (complete with custom chaise lounges).  The ceremony is said to have included a local children’s choir singing Franki Valli’s “Can’t Take My Eyes Off of You” as well as a solo from Bette Midler.  Lively’s friend Florence Welch is also said to have performed.

The sit down dinner (for an estimated sixty guests) was reportedly catered by Mike Lata of FIG restaurant – an award winning dining establishment in downtown Charleston.

Entertainment media were cautious about reporting on the Reynolds-Lively marriage after a recent false alarm.

In July, a police report filed by Reynolds against a paparazzi photographer in Bedford Hills, New York (where he and Lively currently reside) referred to Lively as Reynolds’ wife – prompting speculation that the two had secretly gotten hitched.  Police later acknowledged that they had mistakenly referred to Lively as Reynolds’ wife.

Reynolds – who was voted People Magazine’s “Sexiest Man Alive” in 2010 – was married to Scarlett Johansson in 2008, but the couple separated two years later.  It had been widely rumored that the 35-year-old Canadian actor was “absolutely against getting married” again.

Guess not …

Lively, 25, is best known for her portrayal of Serena van der Woodsen in the teen TV drama Gossip Girl.  Prior to dating Reynolds, she briefly dated one of her Gossip Girl co-stars.

UPDATE: Charleston’s 95 SX is also reporting that Reynolds and Lively were married Sunday Night at Boone Hall’s “Cotton Dock” – and People Magazine is running with the story.
