Actress Jennifer Lopez has refused to pay a $16,000 (GBP8,000) limousine bill, according to reports. The Latina star used cars from New York-based company Spiegel Limousine Corporation while promoting Spanish-language movie El Cantante in July (07). A spokesman for the company says she also ordered cars for husband Marc Anthony, stylist Ken Paves and her sister Linda. He tells New York gossip column PageSix, "Jennifer is being very difficult. We've been calling for several months to collect on the bill. When I asked why they aren't paying, the account person claimed nobody had authorised the transactions." But a spokesman for Lopez says, "The bills were being reviewed because there were some inaccuracies. An amount has been decided on, and payments are being made."
