Gisele Bündchen already has a “best friend” in place.

The 42-year-old model is one of six sisters, one of whom being Patricia, her twin sister. Bündchen has raved over her twin throughout the years, frequently referring to her as her “other half.”

The two shared a rare red carpet appearance this past weekend at the model’s Luz Alliance Gala in support of the Brazil Foundation.

After the event, Bündchen spoke and said, “This was my first Gala and I couldn’t have done it without my sister Pati who worked diligently with the Brazil Foundation to organize this special evening.” “Having her here tonight was incredibly special. As she does every day, she put in a lot of effort to plan this event.

Patricia manages her famous sister’s business ventures in Brazil and acts as her representative.

“I know she’s got my back like I got hers,” Gisele continued. “We trust each other, and that is priceless. We always want what is best for one another.”

Here’s a look at some of the twins’ cutest pictures together, from their first days as babies through their time as business partners.
