Christina Aguilera’s Porta-Potty Is Off Limits to ‘Voice’ Crew

Conan sidekick Andy Richter was randomly milling around the set of "The Voice" when he encountered judges' porta-potties: one for Cee Lo, Adam Levine and Blake Shelton, and another for Christina Aguilera.

Sound the diva alarms! Richter, who tweeted a picture, should have crossed out Aguilera's name to read "Xtina only." Or gone in anyway and belted "Beautiful" at the top of his lungs, attempting to imitate the superstar singer's patented vocal runs.

Since "The Voice" first aired, twisting the staid "American Idol" format to huge success, rumors of off-camera tension between Aguilera and her rival judges surfaced; according to Page Six, Levine can't understand why she's paid $225,000 per episode while he, Shelton and Cee Lo merely net $75,000. He's reportedly annoyed by her outsized entourage, which includes three stylists for hair and makeup.

Aguilera attempted to squash reports of bad blood in last night's finale, declaring her love and respect for her male counterparts. The Famous, for one, is neither surprised nor fazed by her alleged diva-ness. IT'S CHRISTINA AGUILERA. The Patti LuPone of pop.

Wouldn't it be more bizarre if she had only one hair stylist?
