A night out at the South Street Seaport turned bloody yesterday morning when three people were shot outside a fancy lounge.

The two young women and a 23-year-old man were leaving the Front Street bar Stella at about 3 a.m. when they got into a fight with two men, according to police.

A crowd formed, and a man pulled out a .357-caliber handgun and shot the three, then fled, authorities said.

The victims, who were from Brooklyn and Queens, were taken to Bellevue Hospital, where they were in stable condition, police said yesterday.

Cops cuffed two alleged perps just a block away from the shooting. Both live in the area.
