The birthday celebrations commenced on Friday, with Gisele sharing a video in which she and Patricia are presented with a birthday cake. As the camera pans, viewers also caught a glimpse of little Vivian, sitting next to her mom and enjoying the joyous celebration.
Gisele, a doting mother to Vivian and her 13-year-old son Benjamin, was previously married to NFL superstar Tom Brady. The supermodel is celebrating her first birthday since her divorce from her ex-husband in October after 13 years of marriage.
As for her relationship with Patricia, Gisele has spoken about their close bond on numerous occasions and has referred to her twin as her "best friend" and "other half" in various Instagram posts.
Back in May, the twin sisters attended the Luz Alliance Gala benefiting the Brazil Foundation in Miami, where Gisele raved about Patricia.
"My family is everything to me and my sisters are my best friends even if sometimes we disagree," she shared at the event. "Family is what gives us our foundation, they are our greatest teachers, and they help us become who we are."
According to PEOPLE, Patricia currently acts as Gisele's manager and oversees her business deals in Brazil. "I know she's got my back like I got hers," Gisele told the publication after the event. "We trust each other and we always want the best for one another and that is priceless."
Gisele is one of six siblings. Her five sisters include Patricia, Raquel, Graziela, Gabriela, and Rafaela. "When I was growing up in Horizontina, [Brazil], there were six of us girls at the dinner table, six voices rising up to talk or laugh or disagree at once," Gisele wrote in her memoir, 'Lessons: My Path to a Meaningful Life'.
"One day my dad made a rule, if one of us had something to say, we needed to raise our hand." She also added that she had "the best childhood in the world."
