Kylie Jenner (25) is proud: her daughter Stormi (5) has successfully completed voluntary preschool. She announced this to her 393 million Instagram followers with a post.

"My sweet girl graduated from pre-kindergarten today," wrote the mother-of-two along with her daughter.

She kneels next to her daughter and holds a bouquet of roses in her hand. The photo was obviously taken on the sidelines of a graduation ceremony. Pre-kindergarten is a voluntary preschool program for children under the age of five in the United States that takes place in the classroom.

The founder of "Kylie Cosmetics" opted for a casual business look on the special day. She paired an oversized black blazer with a white t-shirt and blue jeans. Stormi wore a white lace dress and ponytail. Some stars also commented on the post. Hailey Bieber (26) wrote: "Grown girl." Model Nicole Williams (35) had the same thought: "Oh, she's growing up."

Kylie Jenner and rapper Travis Scott (32) have son Aire (1) in addition to Stormi. Earlier this year, it was announced that the couple had finally split after five years of dating.
