Bill Cosby's longtime leading lady, Phylicia Rashad, has filed for divorce from her sportscaster-hubby Ahmad Rashad on grounds of "abandonment," the New York Daily News reports. The couple — who have a 14-year-old daughter, Phylea — were introduced by Cosby and got engaged on Thanksgiving Day in 1985 when Rashad proposed on national television. This was the third marriage for both.
