She’s “Irresistible.”

Jessica Simpson, 42, looked sensational in a short yellow dress as she visited New York yesterday, showing off her bod in a long-sleeved minidress with sexy cutouts.

The “Sweetest Sin” singer stepped out in the form-fitting look Wednesday night, with the mini dress gathering at the neck before opening up to a large cutout at the chest.

The dress features a second cutout under the bust and ruched detail on the short skirt, and Simpson showed off a peek of a pale yellow lace bra underneath.

She paired the spring-ready pastel dress with towering metallic gold platforms heels and a matching sparkly gold bag.

She wore her blond hair in long, loose waves, adding large gold hoop earrings and several diamond necklaces along with a white cross pendant.

The fashion entrepreneur sported peach lipstick along with a smoky eye for her night out.

Simpson’s been showing off plenty of standout looks while visiting NYC, like the tight leather trousers and platform boots she wore for her flight to JFK on Tuesday.

The “With You” singer also turned heads in a one-shouldered black gown yesterday, posing in the Grecian-inspired look on her Instagram account.

She also showed off her legs in a brown Elisabetta Franchi skin-tight minidress with sweetheart neckline and knee-high black boots.

The singer — who has been married to ex-NFL player Eric Johnson, 43, since 2014 —  has shared her weight loss journey with fans over the years, revealing how she shed 100 pounds in 2019.

The mom of three told “Extra” that she “went to a nutritionist” and changed up her diet, adding, “I needed to get my eating habits right.”

“I have a lot more energy and yeah, I get to wear all the clothes that are in storage that I saved for Maxwell and Birdie,” she said, referring to her daughters. “Maybe Birdie will outgrow them because Maxwell has already outgrown me!”

We can only imagine what else will be coming out of the star’s archives in the near future.
