Charlie Sheen is now apologizing to Kim Kardashian after an explosive rant he posted on Twitter about her "giggly bag of funk."

Entertainment Wise reports that Sheen posted a tweet, apologizing to the mother-of-one as he is "embarrassed" by his "actions."

Apparently, the American actor was already in a bad mood even before posting the rant.

The former Two and a Half Men star said that he heard a story where Kim allegedly snubbed a 6-year-old girl who just wanted an autograph from the Hollywood celebrity. The story only added to his anger at that time.

The 49-year-old actor wrote in the tweet, which has been already deleted, that the girl "cries about it every night before she goes to sleep" and told Kim to "give something back or go f yourself."

Kim, who was recently married to hip-hop artist Kanye West, have not responded yet to both of Sheen's rant and apology on Twitter.

According to E! News, Kim's rep denied that there was any truth to Sheen's story regarding the girl.

Sheen, who had his show "Anger Management" cancelled, ended his apologetic tweet with the hashtag #ShutUpSheen.

The "Keeping up with the Kardashians" star made headlines in late 2014 as she posed her naked butt balancing a champagne on the cover of Paper magazine.

Kim's butt photo became a source of parodies on the Internet, including men trying to redo the photo with their own bottoms.

The racy photos was captured by Jean-Paul Goude, a French photographer. The photoshoot even included a full frontal naked one.
