A wedding in Pittsburgh's Station Square ended in a bloodied mess when three men were arrested for fighting outside of the reception late Saturday night. The groom, who was among those arrested, reportedly triggered the brawl after allegedly hitting on a pregnant reception worker and then challenging the worker's boyfriend to a fight.

The story is complicated, but let's suss it out. Some time after midnight Saturday night, the groom, Mark Williams, allegedly decided that hey, it was his right as a married man to hit on another woman at his wedding, so off he went to find a reception worker to work his charms on.

Williams reportedly got "touchy-feely" with the woman before attempting to pour alcohol down her throat, though the woman told him that she was pregnant. She called her boyfriend, Tyler Smith, to come pick her up, and that's when things got ugly.

From CBS Pittsburgh:

At that time, Smith allegedly confronted Williams about his actions and a physical altercation began.

Police say Williams' brother, David Williams, 35, eventually got involved and became aggressive with police.

A fourth man, Brian Taylor, 31, punched his hand through the front passenger window of a car nearby. He was taken to UPMC Mercy Hospital for treatment.

Brian Taylor, when being taken away by police, reportedly yelled that he was HIV positive and attempted to resist arrest.

The three men, Mark Williams, his brother, David (an off-duty police officer), and Brian Taylor were arrested and taken to Allegheny County Jail.

A wedding of everyone's dreams! Congrats to the happy couple!
