Britney Spears dazed and miserable?

But as she went through her set for the screaming audience, the singer's dead eyes were a giveaway to the drama going down behind the scenes.

Britney Spears has managed to put on great performances, but throughout her lip-synched show she often looked like someone going through the motions rather than really wanting to be there, NW reports.

And after completing her short set, she came off stage looking dazed and miserable.

An insider says, "Britney was so unhappy. She finished the show and was dazed and seemed on auto pilot. She went through the motions on stage but her heart wasn't in it. She was like a fembot — doing what she had to do to get through the show, but her heart wasn't in it."

Back onstage on the instruction of her father Jamie Spears and money-hungry management team, the fragile 27-year-old singer is said to be on the verge of another nervous breakdown due to the premature push back into the public eye.
