Christina Aguilera is saying goodbye to "The Voice," but it wasn't easy for the singer to make the decision.
"It's bittersweet," the Grammy winner told E! Online. "I so enjoy being a coach to my team on 'The Voice' [and] and at this point in season three, all of us coaches have truly bonded."

Aguilera had fun with her fellow co-stars on-and-off camera.
"When me and Adam Levine are on breaks backstage, you know, we're writing profanity with my red lipstick all over Blake [Shelton]'s trailer while he's napping inside," Aguilera said to E! Online. "It's like we have definitely become like brother and sister. We goof around and play around. I'm going to miss it."
The singer is currently promoting her newly released iTunes single, "Your Body," and her album "Lotus" is coming out in Nov. 13. But she believes her experiences will make her an even stronger coach if she were to return to the show.
"In order to be the best coach I can be on that show is to go out and be able to have the experience as an artist...create new experiences for myself so that I can then come back to the show and share that much more."
Aguilera and Cee Lo Green will be replaced by Shakira and Usher when the new season begins in the spring.
She has already discussed her return to the show with producer Mark Burnett. "He understands that we're artists first," she said. "In order to remain great coaches and to stay relevant, we have to go out and we have to still tour, see our fans one-on-one. I have to feel creatively fulfilled in order for me to then do my job as a coach and be on that show."
She recently told Lucky magazine that fostering new talent is another passion of hers.
"It's a big responsibility to help someone express themselves as an artist. I take it seriously."
