Farrah Abraham Charlie Sheen Feud: 'Teen Mom' Slams Sheen For ALS Bucket Challenge Fail

Farrah Abraham slammed Charlie Sheen on Twitter for what she claimed to be an ALS Challenge "fail."

Seemingly out of the blue, the former Teen Mom took to social media, where she appeared to call out Sheen for pretending to donate money after dumping a bucket filled with cash on his head.

"iCE ICE Baby! #IceBucketChallenge has a lot of #IceBucketFail rather just have a bucket of money that doesn't melt @charliesheen," Abraham tweeted over the weekend, according to an Aug. 25 report by Wetpaint Entertainment.

On Aug. 18, Sheen posted a video online of himself with a bucket over his head. However, when he dumped the bucket out, it was cash -- not ice -- that poured down onto him.

"Oh wait, that's not ice. That's $10,000 in cash which I am donating to the ALS foundation," Sheen explained. "Let's face it ice is going to melt, but this money is going to actually help people.

In the summer of last year, messages sent to Abraham from Sheen surfaced online, and nearly immediately, Sheen put Abraham on blast, alleging it was her who leaked the texts.

In response, Abraham told Radar Online that Sheen was an "old train wreck" with a "crazy" personal life and "horrible" personality. Abraham also alleged she had reached out to Sheen in a professional manner.

While their relationship clearly ended on a sour note last year, Abraham's latest tweet may have simply been her way of commending Sheen for his charitable efforts. Because of her wording, it is a bit hard to tell.
