Meet the Special Guests Singing on Season Two of 'Glee'

Role: A Filipino foreign exchange student whose killer pipes challenge New Directions' brightest star, Rachel Berry (Lea Michele). Résumé: This Filipino pop star — she placed third in the 2005 installment of the Philippines' equivalent of American Idol and has two albums under her belt — began making waves stateside last year. After playing President Obama's pre-inauguration festivities, the 2009 Oscars and appearing in last year's Alvin and the Chipmunks movie, Charice got a big lift this May when she performed on Oprah a week after her U.S. debut hit stores. Hear Her Now: Charice's single "Pyramid," an R&B pop song remniscent of Jordin Sparks and Chris Brown's "No Air," is streaming on her Myspace.
