According to Newsday, Bill Cosby's Nov. 19 appearance on "The Late Show With David Letterman" has been canceled . No reason was given for the schedule change, but Regis Philbin will replace Cosby on the broadcast.

A representative for CBS declined to comment when contacted by The Huffington Post (the network does not publicly discuss its booking process). Cosby's representatives did not return repeated requests for comment; this post will be updated if and when a response is received.

This marks Cosby's second canceled booking in the last two weeks, as he dropped out of "The Queen Latifah Show" on Oct. 30 . That move came a week after stand-up comedian Hannibal Buress called Cosby "a rapist" on stage in a bit that soon went viral. A spokesperson for "The Queen Latifah Show" told The Hollywood Reporter, "Mr. Cosbys 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."

This week, the Internet turned its attention back to Cosby after his team posted a meme generator on his website . The widget was taken down after users uploaded messages that highlighted allegations of rape and sexual abuse brought against the comedian over the last decade .

In addition, Barbara Bowman, one of the women who has alleged Cosby sexually assaulted her , wrote an op-ed in the Washington Post on Thursday recounting encounters with the now 77-year-old comic. She told HuffPost Live in a separate interview that her experiences with Cosby were "sexual encounters that were not consensual on any level ."

Cosby was never criminally charged in Bowman's case or any other. In 2006, he settled a civil suit with one of the women .
