Jessica Simpson celebrates Earth Day by wearing a slip dress and a cowboy hat

Simpson paired her silk-and-lace slip dress with a straw cowboy hat and a big brown-fringed bag and matching booties.

Jessica kept her characteristic flaxen locks down for the family outing, and she accessorized with enormous sunglasses and an overabundance of jewelry.

The platinum-blonde Texan stood by while their daughter Maxwell Drew Johnson doodled eyeballs, stars, and names with her fingers on the dirty back glass of the family SUV.

Jessica posed in front of hay bales with her mini-me, who was dressed in a black Betty Boop T-shirt, blue jean shorts, and $235 Gucci slides.

Joining Simpson was her second husband Eric Johnson.

The couple, who have been married for eight years, also share their $11.5 million six-bedroom Hidden Hills property, which she purchased from the Osbournes in 2013, with their four-year-old daughter Birdie Mae.

‘HEART and EARTH… identical letters,’ Jessica captioned her beachy family slideshow. Just a thought!’

After Amazon Freevee decided not to move through with her half-hour scripted pilot starring John Stamos and Katelyn Tarver inspired by her 2020 memoir Open Book on March 24, the Dukes of Hazzard veteran is currently pitching it around.

It’s unknown when Amazon customers will be able to watch Simpson’s unscripted docuseries with music, which was also included in the cooperation agreement she struck with the streaming service in 2020.

Following a three-year dispute, the former pop star purchased her 18-year-old clothing brand from licensing company Sequential Brands Group Inc. for $65 million in 2021.
