"Anja...since you were born you've been...cute, curious, funny, smart and full of personality!!!" the mom of two wrote across the picture. "Happy 15th my sunshine."

It also appeared that Anja's birthday coincided with her first day of school.

Ambrosio shared another photo to her Story, tagging her daughter, writing "9th grade!!!" across the photo and adding a sticker that read "Back To School."
