JENNIFER LOPEZ is planning to sue fashion designer ANDY HILFIGER after the business partnership on prego J. Lo’s Sweetface label turned sour. Andy and Jenn split after the line flopped at New York Fashion Week in September. It is alleged Hilfiger - brother of fashion legend Tommy - fell out with Jennifer because of her husband Marc Anthony’s hands-on approach to the label. “It is expected that she will file suit and that he will countersue. They’re likely to sue each other,” spies tell the New York Daily News.
