As we reported yesterday, Farrah Abraham and Charlie Sheen have been texting, and she proudly showed TMZ proof of such.

But Charlie was none too pleased about her revelation, and he's now penned an acidic missive to the teen mom that seeks to put her back in her place. Wherever that may be.

Charlie's tongue lashing came in the form of a rejection letter (also obtained by TMZ) in which he lays it all out for her pretty clearly. Read for yourself:

hey, you desperate guzzler of stagnant douche agua;

I truly do not recall giving you permission to globally reveal any communication between us. congrats on surviving your lobotomy and an even bigger congratz on the recent attempt at porn.

your daughter must be so proud.

please send my number to middle earth and if allowed, eagerly follow it into said abyss and slam the door behind you. the world will collectively sigh as the pungent memory of you vanishes into the pedestrian troposphere of lame-suck and zero-life.

oh and I'm sure they'll wave the cover charge when they see your tranny-boobs and five o'clock shadow.

bye!
cs.

Ouch.

But you know what they say -- never piss off a dude who's willing to throw dog poop at a public school building.

Guess this means we won't be seeing any Farrah Abraham cameos on 'Anger Management.' But that's okay. We've already gotten something WAY better.
