Jessica Simpson wears black latex dress on ‘All’s Fair’ premiere red carpet

Jessica Simpson brought star power to the “All’s Fair” premiere in Los Angeles on Thursday, stepping out in a sleek black latex dress by Vex.

The newly single mom of three, 45, stunned in the figure-hugging, floor-length design featuring a high slit and a plunging neckline that dipped nearly to her navel.

She accessorized with layered diamond necklaces that drew even more attention to the daring décolletage, along with statement rings, dramatic silver nails a wavy half-up hairstyle and strappy Giuseppe Zanotti heels.

Simpson makes a return to the spotlight for Ryan Murphy’s buzzy Hulu legal drama, which premieres Nov. 4. The series follows a group of powerful female divorce attorneys — including Kim Kardashian, Sarah Paulson, Naomi Watts, and Niecy Nash — who leave a male-dominated firm to start their own practice.

Simpson makes a cameo as a “very crazy” character who “loses her mind a bit,” as she previously teased to “Extra.” The role required eight hours of daily prosthetics and marks her first significant onscreen acting gig since 2014.

Working alongside Kardashian was a natural fit for the pop star. The two are neighbors in real life, and their daughters — Maxwell, 13, and North, 12 — are best friends.

“To be on set, it just felt kind of natural,” Simpson told “Entertainment Tonight” in the spring. “It was fun to work together. She did all the lawyer talk, I did all the whining.”

Her latest red carpet appearance comes during Simpson’s year of reinvention. She announced her separation from husband Eric Johnson in January after 10 years of marriage.

Page Six exclusively learned at the time that the couple had been dealing with “trust issues” that “drove a wedge between them.”

Since then, the “Take My Breath Away” singer been living her best single life. In July, she told Jenna Bush Hager on the “Today” show exactly what she wants in her next relationship: “He has to be a very good kisser. To me, that’s the most intimate thing. Grab my face and pull me in!”

She also made a triumphant return to the MTV VMAs in September after a 19-year absence, wearing a sheer Christian Siriano gown while promoting her new country music.

Simpson is also performing music live again for the first time in over a decade with a series of shows this fall to support her two EPs, “Nashville Canyon, Pt. 1” and “Pt. 2”
