Christina Aguilera Didn’t Quit The Voice Because of Gwen Stefani.

Earlier this month, the “Accelerate” singer announced she was done with NBC’s The Voiceforever. In an interview with W magazine, published today, Aguilera said it felt like “such a hamster wheel” after doing six seasons with CeeLo Green, Adam Levine and Blake Shelton.

Over time, she explained, “Things really started to shift and change.”
