The singer is suing Hilfiger because their collaboration on a clothing line was a disaster, according to FemaleFirst.
Lopez and Hilfiger were working together to create the Sweetface collection, but their partnership came to an end last year after the line flopped at New York’s Fashion Week.
Andy Hilfiger, brother of legendary designer Tommy Hilfiger, may also counter-sue Lopez. A source revealed to the New York Daily News, "It is expected that she will file suit and that he will countersue. They’re likely to sue each other."
