Anja has already had some practice modeling alongside her famous mom. In November 2020 the mother-daughter duo showed off their matching bikinis from the supermodel's swimwear line Gal Floripa.

During a family vacation in Mexico, she and Anja put on matching baby pink tie-dye ruffled bikinis from the Gal Mini line and posed for an impromptu photoshoot, which she shared on Instagram. "MOM & DAUGHTER 💞 A bond like no other 💫💫💫 Introducing #Galminicollection!!!" Ambrosio wrote.

The sweet shots show Ambrosio and Anja standing on the beach with big smiles on their faces and their arms wrapped around each other in a loving embrace. The duo was also photographed holding hands while walking along the shoreline and laying in the sand.

Ambrosio told PEOPLE that the Gal Mini collection holds an extra-special place in her heart.

"Gal Floripa is all about embracing our femininity and celebrating bonds between women and there is nothing stronger than mother-daughter connection, so in celebration of that we decided to create a collection for mothers and daughters," she said at the time.

"We want to empower younger girls to embrace their inner beauty and cherish those special moments with their moms and remind all the moms out there the importance of taking a step back and spending time with their kids," Ambrosio continued. "I hope that this collection will create a lot of special memories for many moms and their daughters."

Three years ago, the supermodel also posed with Anja and son Noah Phoenix, 9, (whom she shares with her ex Jamie Mazur) for a spread in Harper's Bazaar.

"I want my children to do what they love, and if that's modeling, then I would be there every step of the way to support them," Ambrosio said at the time. "Right now they're enjoying being kids, learning about the world, and exploring."
