Britney Spears is in "vocal shape" for her upcoming Las Vegas residency, according to Caesars VP of entertainment.
Kurt Melien told Billboard that the 'Toxic' singer's 'Piece of Me' show will include 21 of her greatest hits as well as material from her upcoming studio album.
Asked if Spears intends to sing live during her two-year residency at Planet Hollywood, he said: "We haven't had that conversation. She certainly has been a singer and dancer her entire life, and she certainly has the chops today.
"There's no doubt about it that she's in the physical shape and vocal shape to sing the entire show. She's working out a ton, training a ton and rehearsing a ton. She's super pumped and really excited about this idea since it became real."
He revealed that the show will be directed by Baz Halpin, who has worked on productions for Katy Perry and Swedish House Mafia.

"It's 21 of her greatest hits, effectively, and some of the music from her eighth studio album [scheduled for release on December 3]. It's a retrospective on some of the most iconic moments of her life, combined with the more contemporary stuff that she's doing today," Melien continued.
"The show is going to use projection across almost all of the walls, left and right surrounding you. So it's going to feel almost like a planetarium. You're going to have this massive storyline projection around you."
Spears's residency begins with a show on December 27 and she will perform 50 shows across each year of her contract.
Earlier this week, the singer told Good Morning America: "I'm definitely ready. I sometimes have training for five hours a day."
