Grande has never shied away from what she believes she's entitled to.
The legal complaint was filed on Monday morning in US federal court in Los Angeles, according to Reuters.
In the suit, obtained by CNN, Grande's legal team alleges the clothing company sought out an endorsement deal with Grande in late 2018 and early 2019, but the request was "explicitly declined due to Forever 21's unwillingness to pay the fair market value for a celebrity of Ms. Grande's stature".
According to the lawsuit, Forever 21 published "at least 30 unauthorized images and videos misappropriating Ms. Grande's name, image, likeness, and music in order to create the false perception of her endorsement".

Examples of Forever 21's posts depicting singer Ariana Grande that led to a $10-million lawsuit.
The Instagram posts were deleted by Forever 21 in April 2019.
The court papers provide a number of examples, including a February 8 post to Forever 21's Instagram page, which features an image of a model dressed similarly to Grande in the music video for her hit song, "7 Rings". The number seven logo shown in the pop star's music video also appeared in some campaign images posted on Forever 21's Instagram feed.
PEOPLE has reached out to Forever 21 for comment.
In the document, Grande's attorney, Daniel Petrocelli writes, "Forever 21 contacted Ms. Grande's representatives to discuss the possibility of having her endorse the fast fashion Forever 21 brand given that Ms. Grande's fans are squarely within Forever 21's target market".More news: Indonesian police in Papua ban 'anarchist' demos
