For Kim Kardashian, imitation isn't the highest form of flattery. The reality star has sued Old Navy and its parent company, The Gap Inc., for using a look-alike to promote the store's clothes, The Associated Press reports.

According to the lawsuit filed in Los Angeles federal court, Kardashian claims that the ads may confuse consumers into thinking she's endorsing the store's products and that they violate her publicity rights.

The promotion, which began airing in February, features model Melissa Molinaro, who is not named in the lawsuit. Still, she took to Twitter on Wednesday to defend herself. "We're still talking about this?! Its JULY. This aired in February," she wrote.

Kardashian "has invested substantial time, energy, finances and entrepreneurial effort in developing her considerable professional and commercial achievements and success, as well as in developing her popularity, fame, and prominence in the public eye," the lawsuit states.

The suit, which seeks unspecified damages, is asking a federal judge to prevent Old Navy from using a look-alike again.
