Singer Michael Bolton is suing his accountants, claiming they stole more than $5 million (GBP2.5 million) from him. The 54-year-old has filed suit against Executive Money Management at New York's Manhattan Supreme Court. The move comes just a month after bosses at the firm lodged a suit at the same court, claiming Bolton - who they have worked with since 1999 - owes them $500,000 (GBP250,000).
