Married life already looks good on Jessica Simpson.

The newlywed shared her first post-wedding Instagram pic on Wednesday night, on the eve of her 34th birthday. "And the sun sets on 33," Simpson captioned the shot, which shows her wearing what looks like a beach coverup, very minimal makeup and her hair down.

The recent bride is glowing, isn't she?

While it hasn't been confirmed where she and new husband Eric Johnson are spending their honeymoon, it's been reported they'll stay at San Ysidro Ranch -- the same locale they got hitched. According to Us Weekly, they're renting out the same cottage JFK and Jackie Onassis (and Gwyneth Paltrow and Chris Martin) stayed in after their wedding.

The birthday/honeymoon celebrations follow the couple's gorgeous wedding over the weekend.

The pair -- who has two kids together, daughter Maxwell, 2, and son Ace, 1 -- exchanged vows in front of family and friends at the lavish Southern California locale.

"We are overwhelmed with complete happiness and love having made our eternal commitment," they said in a statement to People. "To say 'I do' in front of family, friends and, most importantly, our children has been the happiest moment of our lives."

Jessica had 12 bridesmaids, but she asked her mother, Tina, and her sister, Ashlee, to be her maids of honor. Simpson's father, Joe, officiated the couple's wedding ceremony. The couple's daughter served as the flower girl and their son served as the ring bearer.

Congrats to the happy couple ... and happy birthday!
