The socialite/actress has now explained what happened after a DJ took offense when she asked him to change the techno music he was playing at the posh Fontainebleau hotel nightclub.
Writing on her official blog on Friday, Hilton revealed Reinhardt was left bloodied as six security guards set about him after he stepped in to protect his girlfriend when she was pushed away from the DJ by one of his entourage.
She writes, "All hell broke loose, it was like something out of a fight movie, it was so frightening. I had never seen anything like it in my life. Doug was fighting off like 6 guys. But he was of course stronger than them all, but one of the idiots punched him in the face and busted open his lip. There was blood all over. I cried. I was so upset and scared. It was ridiculous and for such a stupid reason, I cannot believe people behave this way, like ainmals (sic)!"
She tells fans, "FYI this is not in my nature to be in club brawls, I've never been around anything like that. It was totally unprovoked and thank God Doug was there to rescue me."
