Blake Lively Shows Off Her Giant Wedding Ring!

Introducing Mr. and Mrs. Ryan Reynolds!

Blake Lively, 25, and her new husband, 35, are enjoying wedded bliss after their top secret wedding last week in South Carolina -- and in brand new photos, we're getting our first glimpse at her giant rock.

The newlyweds were snapped at Boone Hall Plantation & Gardens the day after exchanging vows. In the pics you can see the couple share some passionate, lip-locking PDA and Blake proudly showing off her stunning Lorraine Schwartz ring.

With a large oval-shaped stone and a couple bands of diamonds, it's one gorgeous accessory ... almost as gorgeous as her hot hubby!

And while it looks like they were definitely having a good time after the big day, it was back to work today for Blake -- who was spotted on the set of "Gossip Girl" in NYC, where she's currently filming the show's finale season.
