*Actress Garcelle Beauvais-Nilon takes the phrase “hell hath no fury like a woman scorned” to a whole new level, as the former “NYPD Blue” star has not only accused her husband of being a big ol’ cheater, but made sure all of his co-workers got the memo – literally.

According to the New York Post’s Page Six, the TV star levels the accusation against her husband, CAA agent Mike Nilon, in an e-mail making the rounds at his agency with the subject line “Tiger Woods/Jesse James/Mike Nilon.” [Story continues below.]

The former “NYPD Blue” standout wrote to Nilon’s colleagues, “What do they have in common . . . I found out today that MY husband of almost 9 yrs has been having an affair for 5 yrs with some slut in Chicago. I am devastated!!!! And I have been duped!! Our boys don’t deserve this!”

The couple has twin sons Jax Joseph and Jaid Thomas, born October 18, 2007. Garcelle also has an 18-year-old son, Oliver, from her previous marriage to Daniel Saunders.
