Bill Cosby's attorneys are asking a judge to dismiss a defamation lawsuit the comic filed against model Beverly Johnson in December, citing their client's need to devote his full attention to his pending criminal case, TMZ reports.

Cosby filed the suit against Johnson in December, saying that Johnson's accusations that he drugged and attempted to rape her back in the '80s are false and defamatory. His attorneys plan to refile the case after the criminal case is decided.

He is currently tied up in litigation with a group of seven women where both parties are suing the other for defamation, as well as his pending criminal case on aggravated indecent assault charges.

Johnson is one of more than 50 women to accuse Cosby of sexual assault. She has publicly forgiven Cosby for his alleged actions.
