Charlie Sheen blasted Kim Kardashian on Twitter, but he later had a change of heart. The "Anger Management" actor previously told the "Keeping Up with the Kardashians" star to go "f yourself" in a post he subsequently deleted. Then, he said sorry for his foul-mouthed rant.

"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," he tweeted. "#ShutUpSheen."

He previously took a dig at the E! reality star in a vicious tweet, "You are lucky that ANYONE cares about your gross and giggly [sic] bag of funk you dare call an ass. your public loves u. give something back or go f yourself. My apologies to your hubby, great guy I'm sure, I hope his vision returns one day."

Sheen's mean post stemmed from a story he heard that Kim refused to sign autograph for a little girl. "She cries about it every night before she goes to sleep," he claimed in the now-deleted message. However, the wife of Kanye West denied the rumor. "I never say no to autographs, especially kids," she insisted.
