Christina Aguilera acting-up on The Voice

Christina Aguilera has been misbehaving!

Sources say the the 30- year-old pop diva behaved like a spoiled brat he most recent taping of reality competition show, The Voice.

“Christina didn’t wave or say hi to the audience. She came out three minutes before the show started and appeared to be in a horrible mood,” a source said.

“She didn’t crack a smile until Cee Lo Green reached out to high-five her. During commercial break, she had about six people working on her all dressed in black and red ‘Team Xtina’ shirts, and one person had a bottle of water with a straw she held as Christina sipped.

“Later, Christina threw her Louboutins on her desk and ran out holding her bladder. Someone ran out to get her shoes in a tizzy and the judges all looked at each other trying to figure out where she went.”
