Jessica Simpson's Post-Wedding Birthday Selfie Is Glamorous

Jessica Simpson has a lot of reason to celebrate so it's no wonder she took a glamorous selfie!

The newlywed, who married husband Eric Johnson over the weekend, took a pretty Instagram snap to celebrate her 34th birthday on Thursday, July 10.

"And the sun sets on 33," the mom-of-two captioned the pic, which shows the blond beauty relaxing in a mysterious honeymoon spot, which could possibly be a tropical location.

In the snap, the style maven rocks a comfy-looking brown-and-white chiffon dress with a plunging neckline and sports a nearly bare face with just a hint of mascara.

Not in sight? Jessica's two children, Maxwell and Ace, and Johnson, who was probably relaxing in the sun.

The couple got hitched on July 5 in front of 275 guests at the San Ysidro Ranch in Montecito, California. Simpson, who was previously married to singer Nick Lachey, wore a custom champagne and gold Carolina Herrera gown.

Happy birthday, Jess!
