MANILA, Philippines - Hours before her performance in a concert, international singing sensation Charice Pempengco was brought to a hospital in Singapore on Saturday morning due to food poisoning.

Pempengco was rushed to the hospital hours before the concert because she was vomiting this morning, her mom, Raquel, told ABS-CBN News in a phone interview.
Nakakain po siya ng [sushi] sa Green Dome. Actually po hindi naman po si Charice lang, halos lahat po sila. Yung iba po kagabi po nagpa-check up na. Yung iba, ngayon kasama niya nagpapa-check up,” Raquel said.
