Queen Latifah -- CANCELS Bill Cosby Interview ... After Rape Allegations Resurface

Bill Cosby won't be promoting his new comedy tour on Queen Latifah's talk show ... because the Queen and her crew got cold feet after rape allegations resurfaced.

Comedian Hannibal Buress called Cosby out last week during a stand up set ... wondering out loud if people remembered Bill had been accused of rape by 13 women over the years. The old news got re-circulated, even though there were not fresh allegations.

Production sources tell us Latifah honchos didn't want the association so they 86'd Cosby. They're particularly sensitive because a video from Latifah's show just went viral, showing a 13-year-old gay kid going crazy on the show after winning VIP Ru Paul tickets.

Cosby has never been criminally charged with sexual assault ... but he has been sued.

As for Latifah ... good thing Jon Cryer is still booked.

A show spokesperson just told TMZ, "Mr. Cosby's scheduled appearance on The Queen Latifah Show was postponed at his request and was in no way related to any of our recent or upcoming scheduled guests."

Our sources stand by the story.
