A man shot a woman, wounded another man and then fatally turned the weapon on himself in Brooklyn during a love triangle clash early Thursday, cops said. 

The 50-year-old gunman blasted the 38-year-old woman in the head and shot the 44-year-old man in the torso and leg on Greene Avenue near Marcus Garvey Boulevard in Bedford Stuyvesant around 3:40 a.m., police said. 

Then he shot himself in the head, and was pronounced dead at the scene, cops said. 

The two victims were taken to the Kings County Hospital Center, where the woman was listed in critical condition and the man in stable condition, police said. 

The violent early-morning confrontation stemmed from a love triangle, police said. 

The exact relationships of each man to the woman are under investigation.
