Charlie Sheen has unleashed a war of words on Teen Mom's Farrah Abraham.

E! News has confirmed that Sheen sent an email (which TMZ published) calling the reality TV star a variety of names and lambasting her appearance.

Abraham first revealed that she had reached out to Sheen in May via text message in hopes of landing an appearance on his hit show Anger Management.

While Sheen reportedly was amenable to the idea, he has since changed his tune.
