Kim Kardashian and her famous family have threatened to take legal action over a beauty product which allegedly uses their name, according to a report.

The stars are reportedly fuming over an eyelash enhancement product called KardashianLash.

The woman behind the product, Sarah Ehrlich, is said to have filed papers to trademark the name, and the Kardashians are planning to fight the petition, according to TMZ.com.

The website reports the Kardashians claim the product infringes their own trademarks.
