It appears Gwen Stefani doesn't "Heart" Forever 21.

Gwen's Harajuku Lovers fashion line is suing popular retail outlet Forever 21 for trademark infringement, claiming the clothing chain allegedly stole designs from the Harajuku Lovers line, Access Hollywood has learned.

In papers filed in Los Angeles Federal Court, reps for Gwen's Harajuku Lovers claim Forever 21 is marketing, promoting and selling products featuring a design "virtually indistinguishable" from Harajuku's signature heart/box logo.

The lawsuit claims Forever 21 "changed a couple of words in the Heart/Box Trademark, which are inconspicuous and likely to go unnoticed by a consumer."

Specifically, the lawsuit claims Forever 21 used the design but changed the word "Harajuku" to "Forever" and the word "Lovers" to "Love."

As a result of the chain using a similar image, Harajuku has allegedly "suffered and continues to suffer damage to its business reputation."

Gwen launched the accessory line in 2005 to coincide with her Harajuku Lovers Tour.
