READ ! Charice returns to 'Glee'

Singer Charice was overjoyed to be asked back for another episode of "Glee," and even more so once she learned she would be singing "All By Myself" by Celine Dion.

"When they gave me the song 'All By Myself,' I was really happy because I've been singing that song forever," she said during a conference call. "I love Celine Dion."

Fans will remember that Dion helped to give the petite chanteuse a career boost when she brought her on stage to sing during a Madison Square Garden concert.

On tonight's episode of "Glee," the young singer will reprise her role of exchange student Sunshine Corazon, who's on hand to help the members of McKinley High's show choir put on a benefit.

Charice said she has no idea if her character's motives are genuine or not.

"I am very excited to see what's going to happen to my character," she said. "Is she going to turn into a spy or is she really going to help glee club?"

She said she's made friends with the "Glee" cast, and was blown away that actress Naya Rivera, who plays Santana on the show, had followed her career. She's also keeping her fingers crossed that she'll be invited back, and would love to sing her new song "Before It Explodes," which was written by Bruno Mars.

For now, she's enjoying the exposure the hit Fox show has given her.

"A lot of people recognize me," Charice said. "'Glee' really helped me in my career and my life."
