Ariana Grande sues fashion firm over ‘look-alike model’

US pop star Ariana Grande has sued fashion retailer Forever 21 for using her trademark style to promote its products without her permission, including adverts featuring a “look-alike model.”

Grande is seeking $10 million over claims the brand, and its spin-off cosmetics line Riley Rose created an online campaign with striking similarities to her music videos, such as “7 Rings,” from late last year.

The lawsuit, filed in Los Angeles district court Monday, claims the campaign was intended to trick consumers into believing Grande had endorsed Forever 21’s youth-oriented products.
