Old Navy has responded to Kim Kardashian’s lawsuit, filed last summer, alleging that The Gap-owned retailer used a Kardashian look-a-like — a “Fauxdashian” as racked.com has dubbed model Melissa Molinaro — in its commercials. Old Navy’s retort? “What are you really worth these days?”

As previously reported by CaseClothesed’s Melanie Perez, Kardashian’s lawsuit claims that Old Navy intentionally cast a Kim look-a-like, creating confusion as to whether Kardashian is affiliated with the retailer, thus violating Kardashian’s rights to her name and likeness. Attorneys for Old Navy’s parent company, The Gap, have hit back by launching an investigation into Kardashian’s “reputation.” The Gap attorneys plan to examine the reality TV star’s actual financial benefit to a brand, including probing into Kardashian’s failed relationship with Bebe and Sears marking down Kardashian-branded apparel even during pre-sales.

Stay tuned; it sounds like the intellectual property mudslinging has just begun.
