CHARLIE SHEEN'S ex-wife BROOKE MUELLER is back in rehab. And at least one trashy tabloid website claims it's Charlie's fault.
--Celebuzz.com says that Brooke fell off the wagon during a, quote, "wild four-day binge" with Charlie a few weeks ago at his house.
--But TMZ claims that Charlie didn't have anything to do with it. In fact, he's the one who got her to go back to rehab.
--Their story goes like this: Brooke showed up at Charlie's house a few weeks ago, and seemed OUT OF IT. So Charlie made her get checked out by an addiction specialist. And that's what prompted her to seek treatment again.
