Christina Aguilera is returning to the reality singing competition 'The Voice' after her one-season absence -- and from rumors that she and fellow coach Adam Levine don't like each other.

A slimmed down Aguilera talked about her return to the program, saying, "It felt as if we never left."

As for her supposed feud with Levine, with whom she's been known to disagree on occasion, Aguilera admitted, "We're both very passionate, but it isn't personal with Adam. It never has been. We're just very strong personalities."

That should be evident from the way Levine has defended her in the past in response to criticisms about Aguilera's weight fluctuations.

The fourth season of 'The Voice' airs on NBC this Monday, September 23. We're just going to cut our losses and assume Blake Shelton will win for the fourth year in a row. Which is something we think the world would be totally cool with.
