Leighton Meester Shares First Personal Pic Since Wedding — And It's A TOTAL Let Down!

You know, Blair Waldorf wasn't this kind of bride — and she was on the run from the cops with Chuck!

Let's see some sparkler, girl!!!

Leighton Meester is certainly beautiful in this first Instagram pic of her (above) since she had her secret wedding with Adam Brody, but she hardly looks bridal in it.

In fact, she isn't even showing off a wedding ring!

Instead, Leighton, 27, posted the picture in honor of John Steinbeck's birthday as she will be in the Broadway production of Of Mice and Men. She added the message:

"Celebrating John Steinbeck's birthday today w/my @miceandmenbway family. @penguinclassics"

That's super sweet and all…but what about some of that sparkle, sparkle she got from her 34-year-old hubby??

Nothing goes better with a classic book than a wedding ring. LOLz!
