'Rude' & 'Demanding!' Christina Aguilera's Biggest Diva Moment Off 'The Voice' Set Revealed

Christina Aguilera brings her diva demands back home!

During her time as a coach on The Voice, the "Beautiful" singer earned the reputation of being difficult to work with on set, but according to an OK! magazine source, she's just as difficult at home. An insider revealed that the mother-of-two is "incredibly rude and demanding" and "treats her household staff terribly."

The singer even "insists" that her staff members "be on call 24/7" to meet her demands. The insider revealed one incident saying, "she has no problem waking up a nanny or maid for the most menial tasks. She's even called a staffer from the other end of the house to get something like a towel that was mere feet away from her!"

The insider explained that Christina's fiancé, Matt Rutler, "does his best to make up for her bad behavior." Adding, "you can tell when he doesn't approve of something she's done. If it wasn't for him, she'd have no staff left!"
