SIR Mick Jagger's first wife BIANCA is being sued by her former lawyer for failing to pay her legal bills. Attorney STEVE WAGNER represented the Nicaraguan socialite, 61, from 22 August 2003 until 31 May 2004. Wagner filed suit in Manhattan Supreme Court last week (ends05JAN07), claiming Bianca owes him $92,609.78 (GBP47,492) for work carried out during that period. He tells the New York Post, "She wasn't paying her bill and she was a difficult client. She was very demanding."
