PITTSBURGH — A woman who appeared with Bill Cosby on an educational children’s TV show as a teenager has sued, saying he defamed her after she gave an interview claiming he sexually abused her in the 1980s.

The lawsuit, filed Wednesday by 48-year-old Renita Hill, says the incidents occurred while Cosby helped pay for her college tuition and housing until she broke off contact with him in 1987.

According to the newest lawsuit, Hill was 16 when she met Cosby during a 1983 talent search for “Picture Pages,” which he hosted.

The lawsuit seeks unspecified damages.
