Less than 10 days after Jessica Simpson tied the knot with former NFL star Eric Johnson, the pop star showed off her summer swimsuit body yesterday (July 14) in a sexy photo posted to her Instagram account.

"Jessica Johnson," the caption simply read, as we see Simpson with a drink in one hand, adjusting her shades with the other, all while wearing a one-piece floral swimsuit. Does this mean that she is ready to change her name professionally?

Simpson and Johnson were married on July 5 at a ceremony at the San Ysidro Ranch in Montecito, Calif. Wearing a custom-made gold and champagne Caroline Herrera gown. Simpson and Johnson released a wedding video yesterday, which gave fans a closer look into the ceremonies, including a closer look at Simpson's dress, the wedding reception setup and Joe Simpson (father to Jessica and Ashlee) introducing to the crowd "Mr. and Mrs. Johnson."

The couple already have two children together: Daughter Maxwell, 2, and son Ace, 1.
