Rebel Wilson and sister twin in matching green swimsuits at the beach

Style clearly runs in the family.

Rebel Wilson and her younger sister Annachi hit the beach on Tuesday during their vacation in Mexico, posing on Instagram in matching green “Coco” swimsuits from Magicsuit ($186).

The one-piece scuba style features a racerback and zippered front, which both siblings wore partially unzipped for a plunging effect.

“Hola Mexico 🇲🇽 with @annachi.wilson,” the “Pitch Perfect” star, 40, captioned her photo of the pair with their arms around each other.

“Looking great twinnies!!!,” commented Wilson’s stylist, Elizabeth Stewart. “Damn girl! Look at you!!! So proud of you. Smoking!!!,” one fan wrote, while another chimed in with, “You look amazing & confident & strong & happy ( most important ) Go girl 🎉👍🏻💪🏻💓.”

The Australian actress’ “year of health” is still going strong. She kicked off her wellness and weight loss journey in January, and has been documenting her progress on social media as she continues her healthy diet and workout plan.

In early October, she shared that she’s just six pounds away from her goal weight.
