Glee star CHARICE PEMPENGCO’s estranged dad brutally stabbed to death in Philippines.

Charice’s father, Ricky Pempengco, 40, was at a small grocery store south of Manila late Monday when he brushed against a drunken man. 

The drunk became enraged and stabbed him with an ice pick in the chest and back, according to the Laguna province police chief, Senior Supt. Gilbet Cruz told media.

A nationwide manhunt has been launched for the suspect, with a 20,000 pesos ($470) award for information leading to the apprehension of a suspect.

Supt. Cruz said at this point the brutal killing appeared random. There was no indication the suspect and victim had any prior grudges.

Charice apologized to her fans after canceling her appearance at a concert so she could return to her homeland.

“I am not going to be there to be part of David Foster and Friends concert,” she Tweeted.

“I have to go back to the Philippines as soon as possible to be with my family.”
