Jennifer Lopez is planning to sue fashion designer ANDY HILFIGER after their business partnership turned sour. The pair joined forces to launch Lopez' Sweetface label - but split last year (06), after the line flopped at New York Fashion Week. It is alleged Hilfiger - brother of fashion legend Tommy - fell out with Lopez because of her husband Marc Anthony's hands-on approach to the label. Now sources tell the New York Daily News that rival lawsuits are being prepared: "It is expected that she will file suit and that he will countersue. They're likely to sue each other."
