After vowing to never return to the singing competition show earlier this month, the 37-year-old singer, who was a coach for six seasons, clarified some of her comments in a new interview with W magazine.
"I signed on to a show where the blind audition element was something interesting, something genuine. After a while, though, you start to see that everyone is good-looking," she explains. "It wasn't a comfortable place for me to be, where I'm just part of a money-making machine. When I stop believing in something, then it's like, 'What am I doing here?'"
"I think I did choose to, no pun intended, take a chair for so long and do something very commercial for my little ones," she adds. "But at a certain point I felt like I'm not even doing them a service by cheating myself and what I'm here to do. They should be seeing Mommy live her best life."
Aguilera, who has two children, Max, 10, and Summer, 3, continued on, telling the outlet that she fought hard to get two females into the famous rotating chairs. The show's current 14th season sits longtime coaches Adam Levine and Blake Shelton, along with Alicia Keys and Kelly Clarkson.
"And, for a long time, I was just told it wasn't the demographic," she says. "But just know that I was a fighter behind the scenes."
"Once again, I found myself in that place where I'm being told what to do, what's going to be acceptable or unacceptable, what's OK or not OK," she says. "It's like, 'God,' you know? I'm a mother of two now. The genie is out of the bottle."
Meanwhile, a source from the show previously told ET, "Christina was an incredibly valuable member of The Voice for many seasons and we appreciate all she did for the show. She'll always be a part of The Voice family."
Despite Aguilera's feelings about The Voice, she fully supports Shelton getting together with Gwen Stefani after meeting her on the show. "I actually think it's really cute Blake and Gwen found love in that chaotic environment," she notes.
