In a selfie posted to Instagram, mum-of-two Jessica looked radiant while sporting minimal make-up, as she posed in a printed halterneck top.
Captioning the photo, she said: "And the sun sets on 33."
Jessica turns 34 today (10 July), and it's a double celebration for the singer and actress, as she's also currently on her honeymoon with new husband Eric Johnson.
Over the weekend (5 July), Jessica tied-the-knot with former NFL player Eric at the San Ysidro Ranch in Santa Barbara, California. Reports suggest the couple are also spending their honeymoon there.
Dukes Of Hazzard star Jessica wore a custom-made Carolina Herrera gown for her nuptials. Jessica and Eric's one-year-old son Ace served as a ring bearer and their two-year-old daughter Maxwell was a flower girl.
Jessica's sister Ashlee and her fiancé Evan Ross were just some of the 275 guests present, along with actress Jessica Alba, her husband Cash Warren, as well as Scrubs' Donald Faison with his wife and Jess' bestie CaCee Cobb.
Speaking to People about their intimate wedding since tying-the-knot, Eric said: "I saw my gorgeous wife coming towards me and she was crying. I think my heart was exploding a little bit."
