Gisele Bündchen celebrated her purple belt with her two kids by her side.
On Monday, the supermodel, 43, shared a series of photos and videos to her Instagram Story after she became a purple belt in jiu-jitsu. In one photo, the mom of two posed with daughter Vivian, 10, and son Benjamin, 13, who all wore matching robes.
Benjamin had his arms around his mom while sister Vivian laid across Bündchen and her brother, smiling for the camera.
"Thank you for teaching us this incredible art that helps us on and off the mat," the Brazilian model wrote over the photo, writing the message in Portuguese as well.

Bündchen shares her two kids with ex-husband and Super Bowl champ Tom Brady, 46.
Jiu-jitsu isn't the only sport that Bündchen's kids play. In October, the proud mom spoke with PEOPLE after a panel for her new partnership with Gaia Herbs in New York City, revealing that Vivian broke her arm three years ago while horseback riding.
"She had a fall. That's another thing, she had a fall and she broke her arm," Bündchen told PEOPLE after discussing her daughter's requests to perform higher jumps on her horse. "Three years ago, and then she didn't ride. She had to put a pin."
"I was there watching that whole thing in slow motion, and it was one of the worst days of my life."
"You would think after going through all of that at 7 years old that you wouldn't want to do it anymore. After a year, after the pin was removed, we started going to ride horses again," Bündchen said. "Just the western kind. It was just easy on the beach."
While Vivian has been horseback riding, Benjamin has been playing football for the first time, wearing a No. 12 jersey just like his dad.
"Benny's doing football," she told PEOPLE, revealing the teen is continuing with dad Brady's tradition of wearing a number 12 on his jersey.
"He just started, and his first game was so nice. It was nice to go because I had all the little friends come to me and be like, 'Oh my God, I love Benny. I love Vivi. They're so nice. He helped me with this.' "
The mom of two later added, "It makes me proud to see how they're all becoming their own little individual selves, but how their principles and their values are so strong. It makes me so happy to see that they're flourishing into their own beings."
