#13: Ariana Grande
Just like many celebrities, Ariana Grande had her own priorities and passions during her high school days. According to her former teacher, she was often absent from school as she dedicated her time and energy to her acting pursuits, which she excelled in. However, there have been claims that she exhibited traits of being a typical stuck-up kid.

Ariana was even accused of displaying some bullying behavior. However, it’s important to remember that people evolve and change over time, and one’s high school self doesn’t define their entire character. Nevertheless, these accusations of bullying are disappointing, especially considering Ariana Grande’s public image and advocacy for kindness and compassion.
