Cops busted a suspect who they say fatally shot a man outside a Queens baby shower last month.

Lhosni Colot, 33, was arrested Monday in connection with the slaying of Tymel West, 22, on Nov. 3 outside the gathering on Guy Brewer Boulevard near 107th Avenue in Jamaica, police said Thursday.

Colot and West had gotten into a fight before the shooting, cops said.

West, who was shot multiple times in the torso, was taken to Jamaica Hospital, where he was pronounced dead.

Colot was charged with murder, manslaughter and criminal possession of a loaded firearm, cops said.
