Pop superstar Rihanna has been ordered by a New York judge to meet with a court mediator to settle a lawsuit against her former accountants. The We Found Love hitmaker is seeking unspecified damages from bosses at New York firm Berdon LLP for allegedly neglecting to properly manage her cash flow and expenses, uncover millions of dollars in unpaid royalties and dissuading her from purchasing a luxury home in California in 2009. She also accused her former financial advisors of failing to file her tax returns, resulting in an American Internal Revenue Service audit. After learning last week (begs14Oct13) both sides want to settle, Judge Kevin Castel insisted the singer appear in court, instead of a delegate to represent her, who she has sent on several occasions while she has been on tour. Peter Larkin, a lawyer for Berdon LLP, tells the New York Post, "(Rihanna) was not there at our first attempt at mediation, and it was a disaster." The judge has also warned the singer to be in court if the case goes to trial and not to try and settle after the trial begins.
