Bill Cosby's scheduled guest appearance on CBS' "Late Show With David Letterman" on Wednesday was cancelled.

Cosby spokesman David Brokaw confirmed that the comedian would not be appearing on the show as previously scheduled but would not say why, The Associated Press reported.

Cosby was also scheduled to appear on "The Queen Latifah Show" about two weeks ago on Oct. 30, but that engagement was also cancelled. "The Queen Latifah Show" previously said the cancellation was per Cosby's request.

These cancellations are coming amid the growing number of woman coming forward alleging he sexually abused them in the past. Cosby has not yet commented on the allegations. 

Cosby was also never criminally charged in any of the allegations despite the detailed accounts some of his victims are saying.

"Maybe he should also teach his fictitious TV family how to escape the talons of sexual predators," actress Barbara Bowman told Mail Online. "Bill used to tell me that he was my father figure and that I needed to trust him as a father, 100 percent. Then he'd drug me and attack me. I was to afraid to talk back. He told me over and over again, 'Trust me like I was your father.' He zeroed in on that like a laser beam."
