Bill Cosby has dropped his longtime lawyer, Martin Singer, amid the growing number of sexual assault accusations against him, according to TheWrap.

Replacing Singer as Cosby's attorney is Christopher Tayback from the firm Quinn Emanuel Urquhart and Sullivan.

Singer was most recently representing Cosby in a lawsuit filed by Judy Huth, who claims that Cosby sexually assaulted her at the Playboy Mansion in the mid-1970s, when she was 15. Singer confirmed to TheWrap that he had been let go by Cosby, but would not say why.

However, a source tells TheWrap that Singer was finding it difficult to retain female clients because of his representation of Cosby, who faces sexual abuse allegations from dozens of women, as well as several defamation lawsuits against Cosby and Singer.
