Jessica Simpson isn't playing around when it comes to having her body in some seriously fit shape, and she wasn't shy to show it off on her Instagram account.  She shared the above photo with the caption: "Jessica Johnson" following her wedding to former NFL player Eric Johnson.

The couple tied the knot on July 5, 2014, at the San Ysidro Ranch in Montecito, Calif., in a rumored $1.4 million ceremony.  She shared the steamy pic, which is likely from their honeymoon, showing the singer-turned fashion designer lounging around in a one-piece swimsuit with a cocktail in hand.

She has yet to publicly say whether or not she is legally changing her name to "Jessica Johnson" despite the picture's caption.

When speaking of their nuptials, Simpson said, "It's an overwhelming feeling to finally be his wife.  We've anticipated this for so long.  It was amazing to feel the love of everybody andd to be able to have our babies and watch us say 'I do.'  It's a moment you can't describe."

Simpson walked down the aisle in a custom Carolina Herrera champagne gown with gold embroidery while her groom wore a John Varvatos tuxedo.  With regard to her choice of dress, she said, "Everybody thought I was going to wear a dress that completely showed off my new bod, but I can't help but want a princess dress!  I'm a southern girl at heart.  I like everything big!"

Johnson commented of his bride-to-be, "She was all lit up and beautiful.  I think my heart was exploding a bit."
