CHARLIE SHEEN Continues Kim K Rant: SHE'S 'A POX ON ENTERTAINMENT'

Sheen tweeted an apology to Kim. He wrote:

Dear Kim, my extreme bad. really embarrassed by my actions. I was already pissed about some other crap that had nothing to do with you. I heard a story that bothered me. wrote some trash you didn't deserve. Ever. I'm an idiot as often as I'm a genius. that day, clearly I was the former. xox c #ShutUpSheen

Charlie Sheen isn't done with Kim Kardashian, telling TMZ, "Zero gratitude, zero awareness, zero talent, a pox on the face of entertainment she is!"

Charlie tells us he actually didn't mean to send the vicious tweet this morning, saying he wrote it a month ago and it accidentally posted Tuesday morning. Nevertheless, he says he stands by it.

Charlie ranted that Kim turned a cold shoulder to a 6-year-old girl who wanted her autograph. Charlie wrote, "Go f yourself," saying Kim's ass was "gross" and "giggly."

Although he deleted the post, he says he stands by his comments. Charlie tells us it's a true story which he heard from C. Thomas Howell. Charlie says Howell told him the girl waited for Kim at a lunch place and politely asked her for her John Hancock when they were alone in the parking lot. He says Kim told her assistant, "Oh God, can you handle this."

Charlie says, "The assistant and dooshy got in her car and pulled out and sped past the poor little 6-year-old without even a glance to the child."

A close friend of Kim's tells TMZ the reality star told her there's no truth to the story and that Kim said "I never say no to autographs, especially kids."
