Page Six on Xtina-Levine tensions

YOU CAN’T MAKE THIS STUFF UP… Oh, wait, maybe you can. According to the lead item in this morning’s Page Six, tensions are bubbling backstage on The Voice between Christina Aguilera and Adam Levine. According to sources, Levine and Blake Shelton have formed an alliance against Aguilera, whose much bigger paycheck, attention-stealing diva stunts and doting makeup team have rubbed the guys the wrong way. "They are all so annoyed by her," a source told us. "Every time she walks away with her entourage, they talk about her behind her back. She holds people up and never apologizes." These chatty sources added that "When the cameras are rolling, she literally won't shut up. It is all about her." The production team is also playing into the rift—Aguilera's supporters wear "Team Christina" T-shirts on the Studio City set. After this big build-up, the item reveals that another source said the judges appeared to be getting along. Levine's rep said, "This is absolutely false. Adam loves Christina, and they just recorded a song together. All the judges had a party at Blake's house the other night after the show." (6/17a)
