Christina Aguilera reportedly annoys the producers of "The Voice" with her indiscipline trait. The singer, who judges the singing talent show along with three other musicians, is said coming two-hours late to the set nearly every single day.

"Christina is consistently about two hours late," a source told RadarOnline.com. "For season three this has got to stop." The execs' strategy was to fine her every time she makes people wait but that's not enough. "Whatever her fine is now doesn't bother her. She has so much money she probably doesn't notice," the insider added. "Higher-ups on the show want to raise it to a number that does bother her so she actually arrives on time."

The other judges, Cee-Lo, Adam Levine and Blake Shelton reportedly were pissed at Aguilera's diva behavior too. "They can't stand how late she is. They know she's a girl and she takes longer to get ready, but this is ridiculous," the source said. "And when she gets to set she still has to go through hair and makeup."

No response from Aguilera's camp so far.
