Jessica Simpson changed out of her wedding dress and into a bathing suit for a new Instagram photo she shared on Tuesday. The newlywed also ID'd herself as Jessica Johnson in the shot, presumably taken on her honeymoon with husband Eric Johnson.
Simpson and Johnson, both 34, wed on July 5 in Montecito, California. The bride wore a Carolina Herrera gown, according to People magazine, which published exclusive photos from the nuptials.
"It's an overwhelming feeling to finally be his wife," Simpson told People.
Whether it's overwhelming enough to alter the name of her fashion empire, perfume and so on remains to be seen. Kim Kardashian kept her last name but added West after marrying rapper Kanye West in May. The change is reflected on her Twitter account. Simpson hasn't gone that far yet.
In her black and white Instagram photo, Simpson lounges in the sun with a beverage in hand. She credited Weight Watchers back in March with helping her get her post-baby body back in shape. Simpson is mom to 2-year-old daughter Maxwell and 1-year-old son Ace with Johnson.
