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.
Sheen calls the single mother a "desperate guzzler of stagnant douche aqua" and goes on to say:
"I truly do not recall giving you permission to globally reveal any communication between us...please send my number to middle earth and if allowed, eagerly follow it into said abyss and slam the door behind you."
Sheen also added, "congrats on surviving your lobotomy and an even bigger congratz on the recent attempt at porn. Your daughter must be so proud."
Yikes…only time will tell what Abraham's response will be.
