Well, this is absolutely horrifying.
SO not okay.
And browsing over Sheen's track record, we wouldn't put it past him!
He "accidentally" shot his own fiancee (Kelly Preston, now wed to John Travolta) in 1990!!!
The Aspen D.A. has said he "cannot confirm nor deny" the fact that Sheen threatened Mueller with a knife, but more information will officially be released through the Police Department on Monday.
