THE FRESH PRINCE OF BEL-AIR star ALFONSO RIBEIRO has filed for divorce from his wife of four years, ROBIN STAPLER. The 34-year-old, best known for his role alongside Will Smith as CARLTON BANKS in the 90s sitcom, cites irreconcilable differences as the grounds for the split. Ribeiro and Stapler met in 1999 while filming US TV show IN THE HOUSE. They will share joint custody of their three-year-old daughter SIENNA. The couple filed divorce papers in Los Angeles Superior Court yesterday (09AUG06).
