Simpson posed in front of a bright mirror in what appeared to be her office, flaunting her curves in a tiny neon green string bikini with a halter top.

She stepped into a vibrant pink pair of high heel cross over shoes from her own shoe brand to give even more vibrancy to the appearance.

The Dukes of Hazzard actress wore her waist-length blonde hair in loose waves and wore no makeup.

‘SKIMS Swim + @jessicasimpson Shoes = Neon Energy,’ she captioned the photo.

It’s unknown if she has been signed on as an official SKIMS model, but the influencer has previously uploaded photographs of herself in SKIMS fashions.

She and Kim Kardashian, the founder of SKIMS, have known each other for many years.

Their children, Maxwell and North West, reportedly became best friends after playing basketball together on a team coached by Eric.

Last summer, Kim hosted a sleepaway party called “Camp North” in Wyoming to celebrate North’s birthday, and Maxwell was invited to attend.

North, according to Jessica, is ‘a wonderful child who will make a difference in the world.’

Last weekend, the 42-year-old fashion mogul Jessica Simpson dressed up in boudoir attire to celebrate Earth Day in Malibu with her family.

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.
