No Doubt’s Gwen Stefani is suing retail chain Forever 21 for trademark infringement. She and her Harajuku Lovers fashion line are claiming that Forever 21 stole designs from them.

Reps for Gwen say that “Forever 21 is marketing, promoting, and selling products featuring a design ‘virtually indistinguishable’ from Harajuku’s signature heart/box logo”. Allegedly Forever 21 basically used the design but changed the word “Harajuku” to “Forever” and the word “Lovers” to “Love”.

Gwen launched the fashion line back in 2005.
