Doug Reinhardt has a bloody lip.and it’s not because of an excessive public makeout session with gal-pal Paris Hilton.

The PDA-friendly couple got into a bit of a bar brawl in Miami Beach early Friday morning, E! News confirms. The pair were apparently attacked near the DJ booth at the Fontainebleau.

Around 4 a.m., as the spinner was playing techno tracks, the BFF-seeker approached him to request a dance tune by Madonna or the Black-Eyed Peas. A nearby bodyguard reportedly got defensive and pushed the celebutante, according to an E! News source.

Like a good boyfriend-take that, Amanda Bynes!-Reinhardt came to her rescue and told the brute to lay off his lady. Things took a turn for the physical, and hotel security had to intervene. Cops were called, but no charges were filed, according to Radar Online.

As the couple heads to an appearance at a New Jersey club tonight, the scratch-free reality starlet will have to nurse her Hills hottie’s bruised, er, lip.
