There's something going on with Christina Aguilera, and it doesn't sound good. In fact, it sounds pretty troubling for both her close friends and family. A new report says the former chart topper has a bad habit of pulling out pieces of her hair extensions whenever she's in public.

The Rumors That Gwen Stefani Is Pregnant By Blake Shelton Have Begun  

According to Naughty Gossip on Wednesday, there's speculation that Aguilera might be having a nervous breakdown as she's worried that she might be eclipsed by Gwen Stefani during the next season of The Voice. Apparently, Aguilera is used to having the spotlight all to herself but will be sharing the stage with Stefani, who is coming back to the show as a mentor.

A source said, "She acts very strange sometimes and no one says anything. Everyone is shocked and just watches her odd behavior but they do not dare speak up or they will be fired. Christina only surrounds herself with people that are on her pay roll. They do what she tells them."

And as far as her hair, the insider added, "She'll throw pieces on the floor in restaurants, restrooms, cars, wherever!"

While Aguilera herself hasn't made any comments about the reports, there are rumors hinting that Stefani has been trying to reach out to her in hopes that they can work together without any drama on the show although sources close to the show's producers say Stefani could potentially replace Aguilera as a season 10 coach next year.
