Talk about some good genes! On Wednesday, Gisele Bundchen happily showed off her sister Gabriela, who was in New York to help the supermodel celebrate her new BLK DNM ad campaign.

"So happy my sister Gabi is in town!" the 32-year-old mom wrote, posting a cute pic of herself with her arm around her little sis on her Instagram page.

Besides Gabi, 31, the Brazilian-born Gisele also has four other sisters: Raquel, Graziela, Rafaela, and her fraternal twin, Patricia.

During the event, both sisters proved to be equally fashion-forward in simple, yet trendy outfits. Tom Brady's wife rocked a green leather zipper skirt with a sheer tank and black blazer, while Gabi wore high heels, tight shiny pants, a white tank top and a black blazer, as well.

Gabi, currently an entertainment lawyer in Brazil, also dabbled into modeling like her big sister at one point. In 1993, Gabi, Gisele and Patricia took a modeling course after their mother suggested it, but Gisele was the one who ultimately stayed in the industry.

Gisele has two children with Brady -- Benjamin, 2, and Vivian, 5 months.
