Former “Cosby Show” mom Phylicia Rashad, 52, has filed for divorce in Manhattan Supreme Court from her husband, sportscaster Ahmad Rashad, 51, according to New York’s Daily News. She is charging him with “abandonment,” say court papers, though the split is being called amicable. Rashad was a star receiver for the National Football League’s Minnesota Vikings before he joined NBC, and Bill Cosby reportedly introduced the couple. (Ahmad’s proposal to Phylicia took place on national TV on Thanksgiving Day 1985.) They have a daughter, Phylea, 14. It was the third marriage for both Rashads.
