Paris Hilton Dumps, Locks Out "Douche" Doug Reinhardt

It's been about 12 hours since we learned the tragic, devastating news of Paris Hilton's shocking breakup with boyfriend du jour Doug Reinhardt.

Now that the dust is settling, the tears have stopped flowing, and we are able to keep food down again, we're looking into what led to the split.

Well, according to reports, Paris Hilton and Doug Reinhardt got into a big fight at The Darkroom in L.A. on Tuesday night, which was the final straw.

The nuclear blowout ended with Paris giving her man, who previously dated LC and Amanda Bynes, the heave-ho before storming out of the club.

But wait, it gets better.

SIX MONTHS IN PARIS: Doug Reinhardt had a heck of a run.

Sources close to Paris say she immediately revoked his privileges to enter the gated community where she lives, so early on Wednesday morning, Doug Reinhardt stood outside the barricade, beside himself, realizing he was locked out for good.

The source says Paris couldn't be happier, as she realizes "Doug is a douche just like everyone tried to tell her and that he was only dating her for publicity."

Well, that about covers it. Your move, Doug.
