Shock and horror! 18-year-old singing sensation Charice Pempengco has just had Botox, popcrunch.com reports.

Charice underwent the surgery before her first appearance on the second season of the smash hit Glee. The 30-minute procedure (which involved an anti-aging skin tightening device and Botox) was apparently used to make her "naturally round face" a bit more slimmer says cosmetic surgeon Vicki Belo.

In an interview Charice admitted that the surgery was part of her preparations "to look fresh on camera", as she felt pressurised to make a lasting impression on her first appearance on the show.

She said: "All people will be anticipating how will Charice look? Is she good enough to pit against Rachel Berry? So of course there is tremendous pressure."

But not Botox pressure, Charice!
