The Queens man who was accused of stabbing his wife to death in front of their 7-year-old daughter has pleaded guilty to the vicious crime.

Balbir Singh, 37, admitted to fatally stabbing Kulwinder Kaur, 29, four times in the chest, shoulder and back during a heated argument inside their Woodside home in 2008.

During the fight, Kaur’s daughter, Bubita Rani tried to come to her mother’s aid when she was stabbed in the arm by her father, according to the complaint.

Kaur continued to defend herself that resulted in 17 other knife wounds.

“This guilty plea is a guarantee that the defendant will be punished for this horrific crime,” DA Richard Brown said. “His daughter will be spared the trauma of testifying about her mother’s death.”

Singh pleaded guilty to first-degree manslaughter on Thursday before Queens Supreme Court Justice Kenneth C. Holder and will be sentenced to 25 years in prison.
