Filipino teenage singer Charice Pempengco says she prepared for her debut on the hit TV show "Glee" by getting Botox and an anti-aging procedure "to look fresh on camera."

The 18-year-old Charice, whose singing career rocketed after appearing on Ellen DeGeneres' and Oprah Winfrey's talk shows, underwent a 30-minute Thermage skin-tightening procedure and Botox to make her "naturally round face" more narrow, celebrity cosmetic surgeon Vicki Belo told ABS-CBN television.

Charice, in the same interview, said last week's face makeover was part of her big preparations for her appearance on the hit show's second season. She starts filming at the end of this month.
