We can't think of a more ridiculous feud!

Backdoor Teen Mom star Farrah Abraham is hitting back at Charlie Sheen following his open letter to TMZ, where he slammed the budding porn star for shamelessly releasing private text messages they exchanged.

"I really don't even care [about Sheen insulting me]. That's coming from someone so old and he needs to get his [life] together. I don't even care. Anything he said doesn't really even make sense to me," she told Hollywood Life.

The Anger Management actor didn't hold back his disgust for the busty brunette, telling her, "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."

His insults remind Miss Abraham of another celeb bully... Amanda Bynes!

"He's meaner than Amanda Bynes. I would never go on an intimate date with Charlie Sheen. He's really not my type at all," she added.

It's too bad these two hate each other, because they would be a match made in heaven!
