A week after Blake Lively and Ryan Reynolds stunned the world for pulling off a secret lavish wedding in Charleston, the "Gossip Girl" actress accidentally flashed her massive engagement ring next to a stunning wedding band while embracing her husband for a kiss.

Lively's engagement ring was designed by jeweler-to-the-stars Lorraine Schwartz.

The rumored 12 carat sparkler showcases an oversized light pink oval stone surrounded by a band of tiny diamonds around it. The ring reportedly cost Reynolds a whopping $2 million.

In an up close photo, Lively's wedding band is a simple rose gold band with diamonds all around.

"Ryan chose Lorraine Schwartz to help him find a flawless, light pink oval diamond," Schwartz' rep told US Weekly. "They worked together to design a custom setting in rose gold and pave diamonds with a nod to deco."

Reynolds and Lively secretly tied the knot on Sunday, Sept. 9 at the Boone Hall Plantation in Charleston, South Carolina, where the classic romance movie "The Notebook" was filmed.

According to the report, Lively wore a custom couture Marchesa gown with hand-draped silk tulle bodice adorned with crystal and rose gold embroidery. 

Attendees revealed that her hair and makeup were very "fresh" and "natural" as she she walked down the aisle to a choir of children singing Frank Valli's classic hit "Can't Take My Eyes Off of You." 

The 25-year-old matched her dress with a pair of matching Christian Louboutin shoes.

"Her dress was simple yet beautiful, slightly off-white, no big bows, no train," a source told People. "She didn't wear anything gaudy; no big jewelry. She had small earrings, and I believe a very delicate necklace, but nothing really prominent."

The stars met and began dating when they worked together on the superhero film "Green Lantern". Not long after the film's premiere, they were photographed in public as a couple in October, 2011.
